We actually don't know if this cute Zelda
crochet block would be a suitable insulator for teapots (and also we're fairly in the dark about the scale
of the thing), but it certainly looks
the part. Maybe you can set your DS down on it, to keep it safe from that hard old table.
Or you can just make it, and look at it to remember the good times you had 1) playing Zelda
games, and then 2) making this crochet block.
There's a diagram available for this extremely cute project at the link (not the Link, but the ... you know), to facilitate your own nerd craftery.
