Our grandson received a Torah for his bar-mitzvah, and wanted a cover for it. I offered to make it. I goggled for a Star of David, and found one to paper piece. I made a practice one, and it was too large. So I put the pattern in my printer and reduced it. Then I made the smaller one. It turned out quite nicely, but ! ! ! when I came to sew the different sections together, I found that I had reduced the seam allowances also. Bummer. But I know how to make 1/8 inch seams, so it turned out fine. Just a reminder: if you are going to reduce paper piecing patterns, watch out for the seam allowances.
Now I have to finish the cover.
