I probably shouldn't be attempting this as yet as I'm quite a Newbie but am trying a layout of my own design. Have everything else calculated - block/sashing/sashing corners/inner and outer borders but am stuck on this.
I am trying to "frame" 9 inch square blocks (9 1/2) but I want to frame them with 1/2 rectangles sewn together (so I can get two colors on each side) to make a 3" wide piece. Using a 3" x 9 1/2" piece cut into the triangle/s and resewn is too short. I know that when you're making half-square triangles you need to add 7/8". Is it the same with rectangles? And do I need to start with a 3 1/2 " wide strip? Tried muslin in different increments......tried the internet. Not finding my answer and really didn't want to use the machine today in all of our storms. If anyone knows I'd appreciate the assist! I hope I'm making myself clear enough or as my Mother would have said - I'm "clear as mud"!?
