Thank you from me too - I have been making bow tucks like crazy too - friends and family and family friends are all requesting them - I have been wanting to try a zipper but didn't know how. I am a little confused - do you add an extra piece of fabric that attaches to the zipper and the inside pieces of the bag? I think thats what you did - because that would give you the covering over the open part of the bag with the zipper. I think I am just afraid of zippers - never sewn one ever. But I am going to try this...Woo hoo...
