Aren’t these little magnets cool? You can make a closure and never see it. But…. how do you install them?????
You can sew right onto the PVC but void the bubble area. That way water cannot penetrate into the PVC and get to the magnet.
Also, Christine suggests another way to install invisible magnetic snaps here. You make a pouch out of fabric (she suggests interface).
If you have additional suggestions on how to install these magnets please let us know at kam@tantalizingstitches.com
