It seems to me that half rectangle triangles are the poor cousin of half square triangles but you can make wonderful blocks with them.
Check out my tutorial on how to make half rectangle triangles.
I don’t have any formulas to make the HRT smaller or larger but it can be started larger or smaller and adjusted. Just tested out!
My book Turnabout Patchwork
“Turnabout Patchwork. Simple quilts with a twist” is all about playing with blocks – making a block, slicing it up, and turning or repositioning the pieces to make a completely different block (sometimes two smaller blocks) to yield endless quilt tops.
- Order Turnabout Patchwork on Amazon
- Order Turnabout Patchwork directly from Martingale (e-book only)
