Found the tutorial here.
Best part (aside from handmade gift potential): I already have a bunch of batik 4-patch from 2" squares ready to go. Original plan was to make some pincushions, but the first one was a bit of a dud (tip: squares of soft foam do not work as well for stuffing a pincushion as I'd hoped), so now I think I'll make a few of these. One of these days.
Finished Butterick 5210.
No pics yet, but will post soon-ish.
