Lots of bags use magnetic snaps. These pictures demonstrate the use of magnetic snaps using the "Girlfriend Bag" by Among Brenda's Quilts. Brenda graciously gave me permission to use her photos.
I plan to add some of the Among Brenda's Quilts bags to my shop, and I already have the Girlfriend Bag pattern on order. If you are interested in any particular patterns, let me know. Brenda has some great designs!
I don't have the snaps on my website yet, either (they're also on order). But if you're having trouble finding these or any bag hardware, let me know and I'll do my best to help you find what you need. I have a Handbag and Tote category on my website, and it will be expanding throughout the year.
