Well I don't know if I will be much help but here goes... I did what you said found a pattern I wanted to do, went to a local printer and blew it up 200%. I had to do it myself, they couldn't do it because of copyrights ( but the patern did say on it to take to a printer and have them blow it up 200% LOL ?) Then I used muslin as the background. I traced the pattern onto the muslin , cut out the fabric and pinned it to the muslin, kind of like putting a puzzle back together. I couldn't find the clover iron on so I just used the 1/4 single fold binding and zig zagged that on. OOppss forgot after I had pinned the fabric to the muslin I made my sandwich, (batting and backing ) so when I attached the binding that was the quilting . Does that help any... There is a book on stained glass quilting .. Stained glass Patchwork Techniques by Gail Lawther.. Good Luck
