Cutting Half-Square Triangles
There this cool new ruler that’s out by Creative Grids and it’s for cutting half-square triangles. This one is to cut 2 ½-inch half-square triangles. So, I thought and show you how it works. And this is kind of like of a two-in-one ruler because on this side, you can cut your strips from the fabric. And then on this side, you actually cut your triangles. So, the first thing I’m going to do is to cut my fabric. I have a straight edge here and I’m going to fold it again so I can cut four layers at a time and then I’ll put my ruler on and line-up this grid line right here which is at 2 ½ inches. And then I can just cut those strips off.
Now I have already cut the 2 ½-inch strip from this other fabric because I’m doing a lock that has half-square triangles. Half of it one patches this fabric and the other patch is this fabric. What I’ll do is put these right sides together and line up the row edges. So, I turn this over so I can where the fabric ends and now I’ll put the triangle beside on here. And what you want to do? This is nice because you got little finger holes here which also work spaces for the rotary for the cutter but, it’s nice because you can really move this around.
So, basically what you’re doing is matching, there’s a grid line here which is bottom of your fabric. And then the end of the ruler which is here and that means we wind up on your fabric then you just and then just start cutting. So, you cut that one and then if you are really clever, you can cut like that. And just keep your finger out of the way and just cutting back for it. Now once I’m finished, I’ll let this ruler up and then separate this. And the thing is now I’ve got half-square triangles because and there is no wasted that fabric.
So, I actually out of this piece got nine half-square triangles. And they are ready to take to the sewing machine because they are facing right sides together, all I have to do is take them to the machine and stitch along that edge. And then also because I can change did some they’ll just to go to straight through.
So, that’s pretty cool. I can just say its creative grid is makes it. This is 2 ½-inch half-square triangles. You can also get isosceles triangles and bigger of half-square triangles.
