sewhappy30, I went to Quilter's Cache, too. I do like your suggestion of the zinnia block as a replacement for the compass block; I've added it to my list of possibilities. Thanks!
Several blocks caught my eye when I was on the site. The "Star and Crescent" block is from the 1920s and has the white open space around it resembling the JT2 block. I also like the "Children Take Wing" block, and the "Evening Star" block could be adapted. Unfortunately, they aren't historic. Guess I'll have to decide at some point.
Thanks again for your help!
