Pieced Squares - Introduction to Half-Square Triangles

Watch our video...

Tricia Camp demonstrates an easy method for stitching half-square triangle units, starting with 2 fabric squares. Includes tips on figuring cutting size and trimming units.

Step-by-Step Instructions...

Step 1. Determine size to cut squares

The formula for cut size of a square to make a pieced square of half-square triangles is: side of square + 7/8˝ (e.g. finished square = 2½˝, cut size of square is 3 3/8˝).

Step 2. Mark and Sew

Draw diagonal line on wrong side of lighter square. Referring to Diagram I, place marked square on darker square, right sides together. Sew ¼˝ seam on each side of marked line; cut apart on marked line. Open and press to make 2 pieced squares.

Oversizing the Square

One method that has worked really well for me is to actually increase the size by 1 full inch, follow the marking, sewing and cutting directions, but then trim the final block to the required size. This gives you a little extra to trim off (extra step) but well worth it. also there are papers out there that help with hst - just google hst papers

Video format

I am unable to view your videos on my iPad. It would be nice to be able to view these in my craft room or while sitting on my couch. Ay thoughts on changing format so it can be viewed on phone or iPad? Thanks!

Response to soyasauce

Hello, I would recommend more practice, paying careful attention to both marking, and stitching straight on your marked line. I have found a very helpful product, Clearly Perfect Angles by New Leaf Stitches, that aids me in stitching a straight line from corner to corner. Their website is www.newleafstitches.com. Thanks for your comment!
