Those charms are great. Oh how I wish I'd have better luck finding really lovely charms. I'm soooooo over the crappy selection of Charms my beloved Joann's has had lately and I've been way too busy to cut my own. I really like the pattern as is although I can understand you may have the need to lengthen the straps. I still think it's darling though! I'll have to check out that pattern as well...
Explosive blessings, abundance and inspiration to you all!
