i finallly figured out what to do with that wooden cassette tape holder. come to find out, each slot is approximately the same width as a one by two piece of wood. just a little sanding is required to make them all fit.
as it's christmas time, i decided to make a festive phrase, in a festive font. i tried using the modge podge and gel medium technique to transfer the image, and had only marginal success (i think i was too impatient and ended up rubbing off some of the image). i filled in the rest with a sharpie, and i think it turned out quite swell.
and i made plenty of more blocks, so that i can trade out the phrase when christmas decor is no longer appropriate (which, the way things go in my house, is round about february).
