Last you saw this wall-mounted bottle opener (see here), I had not yet hung a cap receptacle. I fixed that this afternoon after picking up an ASKER container at IKEA. The ASKAR is flat-backed, so it hugs the wall nice and close. The bottle opener, by the way, is the Classic Zinc Starr X from Amazon. [...]
Before: After: Done and done. I'll hang something below the bottle opener eventually, but for now the caps fall into a small pail. After hanging items on our cardboard & playdough lathe & plaster walls, drilling straight into solid wood felt goddamn luxurious. Cheers!
