This doesn't seem to be working out...
I just started on a simple baby quilt pattern called "Traveling Southwest" that I found on FaveQuilts. It says to cut 8-1/2" squares of print and background, draw a diagonal line on one, layer a print and a background and sew 1/4" each side of the drawn line, cut, then put with a 7" square of print and one of background to form a sort of arrow pattern.
The dimensions don't work at all. If I had the "geometry gene" I could figure this out, but what is wrong here? It seems obvious that the 8-1/2" squares are too large, but I have never been able to 'see' how a measurement will turn out after taking some seams, cutting, etc.
