How to Cut & Sew Triangles for Quilting (60° Equilateral Triangles)

hi I'm wonderful my Lander craft and today I'm going to show you how to cut triangles using a straight rule one using a triangle ruler and also using the 63 degree line on your mat and also at the end of this tutorial going to show you how to slow them together so let's get started Oh so I want six inch triangles for my project so I've cut my fabric into six inches and width and I've removed the salvages and I have the sandwiches on my left-hand side and I have the fold on my right-hand side so what we're going to do now is take our ruler and you can see here that I've put a piece of tape on the 60-degree mark just to make it easier for me to find and I have the pointy piece where all of the lines meet facing to my right and we have a line the 60 degree line flares out I have that on my lick going towards my left so what I'm going to do is I'm just going to turn the rule around so the 60 degree line lays along the edge and I'm going to just move that out until it lines up with this point at the top so just get everything nicely lined up so you can see here I have the 60 degree line and my point is all on the edge of my fabric and my ruler is at the point here now if I cut at this point I'm going to end up with two pieces of scrap here but if I want to have these pieces where I can use them in my project so they will make two triangles I need to move it over a little bit and I actually line this up with the quarter inch line so that's going to give me a quarter inch seam line and I can then use those pieces of fabric in my project or in another project so just make sure that everything is lined up nicely there we go some sixty degree line quarter-inch seam allowance and we're ready to cut there we go and we have two bits that we can still use just put those aside now I'm just going to take the ruler and move it so that the sixty degree line now goes along my cut line I still have my point on the on the edge of the fabric and just make sure that that line is nicely lined up along my cut line and then I'm going to cut once again you are I have my two triangles and then do the next one we just come along and line ourselves up again this time we want it to go to the point because we're not having to add a seam allowance okay so on a line at a point we'll lined up nice and lethal on the edge and coming out at the point and we'll just cut that and that's how you cut triangles using your ruler so now I'm going to show you how to cut triangles using a triangle ruler I'm using a slow easy 60-degree triangle and what I like about this is it has the center of your triangle marked here so there's a center line and it also has the quarter inch mark on either side of that center line so that's your seam allowance so I really like this ruler now I want 6-inch triangles for my project so I've cut my fabric at 6 inches and width and the first thing we're going to do is we're going to get rid of the excess at the end here to start with so I line up my ruler on the six inch mark and I have the point at the other end now if you don't care about those scrips you can throw them away that's what you'll do you'll just line it straight through at the point and bring it and come straight through there when you're cut but however if you wish to use those pieces in your project you'll need to add a seam allowance so we just move it over to the quarter inch so I got the call four inch line there and we're going to cut like that some on my six inch mark got my point at the edge a little flap here but I'll show you what we'll do with that in a moment so I'm going to make my cut and then what I'm going to do is I'm just going to cut that little flap off okay so then you I you have two triangles with the seam allowance that half triangles that you can use so I'll just pop those aside now what I'm just going to do is flip my ruler again lined us up on the six inch line and my point comes to the point here sunshine yep okay so down the edge of where our cut was got a six inch mark along the edge and we've got our point up here and again we're just going to cut whoops sometimes happens we will have little mishaps okay that's those triangles and now flip the ruler around again I find this easier than flipping the fabric I think it's a much quicker way of doing things again we're going to line up on the edge of our triangle we've got our point up the edge there and our six inches along here and cut quick and easy this isn't we're doing two at a time so it's going to be done in local hook let's do one more turn it up down the edge of your cut on the edge of our fabric point at the end here and cut here we are six triangles cut and two halves and no time at all so now I'm going to show you how to cut triangles without any fancy rulers simply with your mat so I need six inch triangles for my projects I have my width of fabric here cut at six inches I've taken the selfridges off and I have the open end that's the formerly selvage end facing to the left I have the fold facing to the right so what I need to do is just find the 60 degree line on the match and you'll see that it converges down here with the 30 degree but that's the one we're going to be working with 60 degree so we're just going to line our fabric up on the bottom line here and into the corner and along the edge so edges are lined up we're in the corner now we take a take a ruler I'm using quilters slider block and you put it to the end to that corner where the lines meet and go along put it along the 60 degree line there now you can just go ahead and cut that but what that'll have to do is will give you two pieces that you will just have for scrap so you can't use those so if you do want to use those as a half triangle or half a triangle you're simply moving along and leave a quarter inch seam so now I when I line up I have a quarter inch that sort of goes in under the ruler and you'll be able to use that in your project so again we're all lined up more on this 60 degree line and we're ready to cut and there we go but our first cut and those will be able to use those now what I'm going to do next so I'm just going to take my fabric and turn it over and line that up with the corner and again along the edge take my ruler didn't mean to do that okay lined it up from the corner along the 16 succeed agree edge and cut again turn the fabric towards you take the top point to the corner place your ruler along the 60 degree line and cut and that's all you need to do it so you don't need a fancy ruler you can just use your mat so now that we've cut our triangles I'm going to show you how to sew them together now one thing you need to know about triangles is when you cut them you'll find that they have a bias cut on two sides and that means that it's stretchy so if you pull aside its still see how it stretches and the same with the other side but the bottom piece doesn't stretch much at all let's across green piece and that's the piece that you want to have at the edge of your project so I usually put mine in two piles for my triangles on two piles and cut them together so that on the cross green side so I know exactly which side needs to go to the edge so now that we've cut our tracked triangles we need to sew them together so the first thing we're going to do is lay them out on our mat and what you need to just look for here is that you have the non stretchy part remember we talked about that before so just give it a pull you can see that there's no given that so that goes to the edge to the outside edge and the seam with this piece goes to the outside edge so all your triangles along here will have the non stretchy piece facing to the edge now the same will happen on this side you can see here this is non stretchy so that's a cross green piece and that comes here and all these pieces you'll have the cross green piece facing out towards the edge now we're going to sew down our bias strips and those are the stretchy bits so we just make sure yes we've already checked it but we put our stretchy bits together and we sew down there with a quarter inch seam okay and then we'll give us a piece that looks like this now don't cut your dog ears off at the stage because these will help you to align your next triangle so take your triangle and just lay it on top again these are the stretchy boots which I soaked with a quarter inch seam and then we'll end up with a piece like this now you can keep going like this you'll just keep adding triangles and you make a strip of fabric as long as you want it to be and the same you can make a full quilt with just rows and rows of triangles and they'll have really effective now we have a an upcoming tutorial where we put together some triangles to make this table runner so what we've done is we've done two rows of triangles and then we've just signed them together and edit some borders so we'll put a link for this tutorial in the description below once it goes up on to youtube so if you've enjoyed this tutorial give us a thumbs up and subscribe to our Channel and the full written instructions will be over on our website so
