(Hi , Lin!) So here goes. Hope you will give it a try.
How to make Half Square Triangle Blocks with Selvedges.
Or... how I make them anyway!
For my latest little quilt (36" x 36" ) I made 13 faux HSTs
First, gather your selvedges. For this project I used my low volume ones. I usually sort all my selvedges into colour families but they look great when sewn together randomly too.
Next, press and sort.
For the foundation, I used 9 1/2" squares of solid grey fabric. I use this size because it is the size of my favourite ruler. You can make your squares whatever size you want.
Draw a line across the diagonal in one direction. The line will be covered so don't worry about it showing.
Choose the first selvedge you want to add, making sure it extends at each end. Place it directly on the line, pinning if you desire, and sew very close to the edge. I used a dark grey thread but you may prefer white thread.
choose your next selvedge, again making sure it extends past the edges at both ends. Position it so that it covers the previous selvedge by about 1/4 " and sew very close to the edge. If you are making several blocks you can chain piece too!
Keep adding selvedges until the surface is entirely covered.
Time to trim it up even with the foundation square
And now you have a perfect Selvedge HST to make any number of different designs.
Hope you enjoy sewing up your blocks and make sure to share your creation with me.
