Welcome from Florida, but my heart is still in the Seattle area where we lived for 18.5 years. As for your question, you have some outstanding quilt shops in your area...if you are comfortable asking, seek their advice. But if they are competition, then I agree with Jane Quilter. Basically, buy several products and make samples, wash, display...all good ideas. Personally, I have used Heat n Bond and Wonder Under, but I always sew the edges on my applique. Wishing you good luck in your endeavours.
