Cutting HST from sewn strips...

Aug 27, 2006 11 Replies

I own the Creative Grids angle ruler that lets a person cut half-square triangles from sewn strips. I can't find the accompanying instruction sheet (strange for my tidy sewing area!). I know that you sew two strips, let's say one blue and one yellow, to each other. I think you sew these on both sides. Then you take the 45-degree triangle ruler so that (if you want 2" finished squares) the 2.5" line sits on the stitching line on one side. But I'm not sure if that is the correct dimension, or how wide to cut the strips. Can someone who has this ruler refresh my memory? I've been through all my books and patterns twice, and this little laminated sheet is hiding from me!

hi Jo, i dont have or use that one but on every other HSTs method i've seen, you need to use 2 7/8" for 2" finished. its 2 + 1/2 + 3/8. the extra is cuz its a diagonal line. i've made them with 2 starting sqs and on a grid, not strips but i cant see why that would be any different. i'd cut the strips 2

7/8" and cross cut into same size to get two finished 2" hsts. not sure if that makes sense but fwiw, hope it helps or someone else chimes in here soon. cheers, jeanne

Nope. The 7/8 thing is only if you cut squares then make the triangles.

It's been a while since I did that method and then I either used the Bias Square ruler or just a plain old ruler. But yes, you cut 45 degree on your strip and then move the ruler the width of you desired half square triangle block. So, for 2" finished you would move it 2 1/2" and cut. Then you have to square up the other two sides if you are using a regular old ruler. I always over cut my strips. I'd rather lose a little fabric than be short because of a wobbly seam. For a 2 1/2" square I'd cut my strips 2" each.

wow, you can tell i've no idea how that method works, lol, tho sounds interesting. could you please explain it a bit more clearly for the foggy brain here. re your last sentence.... how do you get 2 1/2" sqs when you cut a 2" strip? cheers, jeanne

Say you're making lime green and black half square triangle blocks.

Cut one strip of lime on the bias Cut one strip of black on the bias

Sew the two strips together. Then with your ruler at a 45 degree angle, cut the end of the two color strip. Slide the ruler 2 1/2 inches and cut again. You have a nice two color parallelogram. Then turn your parallelogram so you can cut the other two sides to make a 2 1/2 inch square.

If you have a bias square ruler than you can lay it on the strips with the point on the seam and cut the bottom two sides of the square, then slide the ruler down and cut the top two sides. There's a picture at the bottom of this page:

By using bias strips you end up with the straight of grain on the outer edges of the squares after cutting.

ah, those kinda hsts, got it now, ta, marcella. poifect colours you chose for those hsts, lol now i see why you only need to cut the strips at 2" across, doh, silly me. tho must say i'm not fond of the folks at that site/chatroom. they're the ones who called me a cheat and a liar and booted me out of their chatroom. i neither cheated nor lied about anything there and they did not like me using my own last name as part of a silly user nickname in the middle of the usa night when few were in chat then to be offended anyhow...seems it was something within the narrow little dirty minds of the other good ladies who chatted there. their attitude is not forgotten. oh well. :) cheers, jeanne Say you're making lime green and black half square triangle blocks.

I picked those colors with you in ming :-)

I didn't even know that site was a chat room....I just searched on bias half square triangles and got there. Well, phooey on them, I'm glad you came here instead!

Good luck with the plumbing!

marcella

Thanks for that!Especially starting with bias strips! duh. lol

This ruler doesn't use bias strips. Thank you for your instructions however. I have written to the company to see if they can send me another sheet of instructions.

Well now, Jo, I just hate to state the obvious - but why don't you just stitch some strips together? Then, try this and try that? As smart as you are, I just know you'll have it conquered in no time. Sweet talk the Sasha for us, unless of course, she finds such displays of affection offensive. Polly

Does it work like the instructions for the Wonder Cut ruler, as shown on the following page?

I use neither of those rulers, but this does look like what you described.

Keep in mind that if you cut your strips on the straight grain, all your squares will have bias edges. You may want to cut the strips on the bias.
