It’s been awhile since I’ve done an update! My life has been consumed with making HST (half square triangles) for the Tetris quilt. A HST is made up of two 45 degree right triangles:
A few posts ago, I put up the block design, which is a square with 4 trapezoids. The actual assembly of the block has quite a few more pieces, to make it easy to assemble. So it’s actually 1 square, 4 rectangles, and 4 HSTs. And the quilt has 188 blocks (47 Tetris shapes times 4 blocks per shape) = 752 HSTs. Oh, and the finished block is 4″, so each HST is only 1″.
The typical way to make HST is to make them 2 at a time. However, there is a really cool method to make 8 at a time. You start with a large square (“large” being relative in this case, since it was only 4″). Then you sew 1/4″ on either side of both diagonals, like this.
Once you do that, you cut the square into quarters, using the line intersections as a guide.
Then you cut each piece along the diagonal
Lastly, you press them open (this one hasn’t been pressed yet). And since I want all of my seams to nest, which fabric gets pressed which direction is important.
I spent a few afternoons doing the sewing/cutting, then spent the last 2 evenings pressing the HSTs open. It took me five and a half 40 minute television episodes 😀
Up next… all 752 HSTs need to be squared up to 1.5″………
