Whew! It's been a long time since I've been able to sit at the machine and cutting board and enjoy making a quilt. I started on a new one, Flight of Swallows.
Yes, I know, I've got a glorious amount of piecing potential already started, but, like I like to tell people, it won't go bad on the shelf and someday, I might get to them.
Ahem, one of my favorite things to make are half square triangles and my preferred method is using a grid on fabric. Working on the wrong side of the fabric and
increasing the size of the block by 1/8 inch, I drew 2 7/8th inches squares then drew my cutting line, along which I sew my 1/4 inch seam. Keep your needle down and pivot
and the corners. 
This is how my husband and I spend some evenings,
me at the machine and him on the PC with his trusty Law and Order on TV....Aaaaahhhh, I'm feeling simply quilty, right now, at least.
Happy Quilting!
