HelenW, thank you very much! The green fabric was a lucky find in my stash.
I'm refreshing/learning skills for hand applique in the quilt. This is just what is currently working for me -- Jeana Kimball #11 straw needle and WonderFil Invisafil 100wt thread.
Generally, I use needle turn applique with templates or back basting. Thanks to TQS, I was introduced to the Rosa Rojas Aplliquick method. For the most part in these blocks, I used her technique together with a new product (to me) for the template material -- Quilters Select Print and Piece Fuse Lite. For my skill level at this point, it was necessary to keep sharp-point areas free of any glue and fusible and to just mark the fabric in these areas for needle turn applique. Otherwise, this approach was a great new experience.
For the circles, starch and Karen Kay Buckley's mylar templates are what I reach for.
