Need some "math" help
I embroidered a guitar and when my daughter saw it she said it would be an awesome Christmas present for my 18 year old grandson - we can make 4 of them, then quilt blocks surrounding. It sounded like a good idea. So....got the guitars done - each is 11.75 long by 4.25 wide. I embroidered them on a 18 x 10 fabric. I'd like to do them as either a D9P or D4P but the math scares me......
The tutorials on both start with 5" charm packs. I have fabric to cut. D9P = three(3) 5" squares, with seams it becomes 15 inches minus two(2) 1/4 seams in the patch = 14.5" and that would work for the length, but not the width.
The D4P starts with 5" squares but has 3 seams so 10"-.75" for seams = 9.25 good for the width, but now the length is off.
Am I counting right, and how could I re-jigger the cutting to make this work? I don't want blocks that are too tiny, as the prints aren't too tiny.
Another easy/quick pattern idea?
