I have a package from Butterick #4308 that has about 12 different iron on transfers. Never used, just opened it this morning. I doubt this is the eagle you are talking about but will describe it.

The pack says "Americana Embroidery. Embroidery transfers based on authentic early American designs and super Bicentennial subjects with stitch instructions included. Pattern includes at least one of each motif sketched. Yellow transfer stamps once on most light or dark fabrics (except yellow)."

The only eagle design is a spread wing with a red/white/blue shield on the chest and either arrows or a branch horizontally through the tail area. The design measures approximately 6" high by 7" wide.

I just checked Ebay and this exact pattern is on there. There is also one other Vintage Americana transfer by Simplicity. At least that gives you pictures to check out.

Thanks for checking, Lynn. I do appreciate the effort, but I'm afraid that's not the eagle I'm looking for - it was larger, and the wings were more outspread than up.

I did some more looking on eBay, and didn't see it anywhere. I'm going next week to my parents' house to help get it cleaned out so they can sell it and move to something smaller - maybe the pattern will surface there!

Thanks again!
