For a few weeks I have been searching all over for some of those strong donut shaped magnets — I checked mom and pop hardware stores, craft shops, drugstores, strange discount stores and even the surplus section of Archie McPhee. Yesterday we were in a Radio Shack (don’t ask) and there they were. And now my shower curtain doesn’t billow in, bliss.
Note to self: they also had tiny rare earth magnets and the disc magnets for making marble magnets (perhaps stronger than those from a craft shop?), and they had a big old tube of silicone sealant, which people still ask me where to find.
