    Tip for Saving Scraps: Half Square Triangles

    Feb 7, 2013

    I’ve been using this trick to save my scraps and make half square triangles while I’m at it.  It’s a great method to use when your adding stitch-n-flip corners to a block.  
    Lay the square in the corner of your block with the pencil line like so:
    And stitch down the line as you normally would.  Instead of trimming and throwing that whole corner away, sew a second line ½" away from the previous seam towards the corner like so:
    Then cut in between the 2 seams:
    Press, and you’ve got your block with the triangle corner, and a half square triangle.
    The half square triangle will be 1" smaller than the original corner square you sewed on.  So this corner square was 4", and my half square triangle is 3".   This is a great trick for patterns like Pow Wow where the corner squares are large and it creates a lot of waste. 
    Then you’ll have lots of little tiny HST’s to make another project!!!  Because all you needed was another project right??!  ;)

        Well I just did this a few weeks ago and I was sure it was a new tip but I guess I am late to the party. I have about 400 1.5 inch perfect half square triangles.

      Great idea to share! I did this once with a pattern I was making and the leftover HSTs were 1 inch! I used them to make mug rugs! There was as much fabric in the seam allowances on the back as there was on the front!

      That's a great idea! I am nowhere near organized enough for that, but I think it's cool anyway. Like people who not only cook Thanksgiving from scratch, but also have gourmet casseroles and panini sandwiches planned for all of their turkey leftovers. You go, girl! :-)

      I need to start doing this. It's a great idea. Because if they aren't already sewn together, and just trimmed off, I have found that I will probably NEVER sew them together...

      When I made my son and daughter-in-law a quilt two Christmases ago, I had a lot of half-square triangles left over. I used this trick and turned all the extras into a matching quilt for their pug!! It was a win-win situation!

      I made this when making my Swoon blocks and will possibly have enough HSTs for a zig zag pillow matching my Swoon quilt once it will be finished. I mark two lines that I sew on instead of one but the rest and the effect is the same. I read this tip at Fromthebluechair.

      I was just getting ready to start a project that use that technique and was thinking there has got to be an easier way to save and use those HST that I trim. Thanks for the hint.

      That's such a great idea. I never save all those little triangles because if they're really small they can be such a pain to work with... but I could totally find a use for a bunch of little half-square triangles! Thanks for the tip. Why didn't I think of that?

      I learned this tip in a quilting class. I thought it was so clever and do this when I can. I have quite a few, now just need to come up with a project for these small hst. What do you do with yours?

      I always do this! Between this and using enders and leaders and chain piecing, you can end up making multiple quilts at once in almost the same amount of time (and save money!). One other tip to add: Press the block for the first time to set the stitches before cutting off the hst - cuts down on the ironing time, too! The one thing I've learned, though, is be sure to buy some extra background fabric. I have tons of wonderful teeny tiny chevrons I put together from tiny hsts, but I can't get any more of the great white background fabric that I used, so my awesome design idea went by the wayside! I'll have to rethink it!

      I ususally sew on both sides of the diagonal line. I made a "hugs and kisses" quilt and with the scraps I made my "pinwheels galore". Great tip!

      I just finished a queen sized quilts using mostly left over scraps turned into hst's that I did for a year. I do have the advantage of having a go cutter so it made it real easy to cut a stack of scraps at a time. Just over a year I had enough to throw together a quilt for a wedding gift when I suddenly needed one!

      Have been trying to get myself motivated to doing some sewing and eventually some quilting. Have new machine bought early last year have hardly used it. Had right shoulder replaced on 12/7/15 so had to hold off for while but want to get to it again, used to do lot of sewing and miss it. Your tutorial is very clear so even I can understand. You do beautiful work. Have subscribed
