Popping in to show off my completed string top.
I added piano key borders top and bottom.
It now measures 60 by 65 inches.
I'm basting and quilting it this weekend.
Some people left comments saying they prefer using paper foundations instead of fabric.
I hate tearing off paper,
and because these fabric foundations are 1/4 inch smaller all around than the block,
I don't have the extra bulk in the seams allowance.
I think both paper and fabric have their advantages.
I'm machine quilting this, so I'm not worrying about the extra layer.
