Hi,
It really isn't a hard pattern, it is a tad time consuming, tho...lol...For making ornaments, it should go pretty quick, and if you stitch the curves by hand, that is a portable craft that you can work on anywhere, eh??..In addition to the great tut on here, if you google cathedral window quilt block pattern, you will find several ways to do it, all along the same lines, but different techniques from different people... Lastly, thanks for the link, as I think I may have to tweak them and come up with something, too...
Good Luck,
Kif
