Bwahahaha, I'll kill two birds with one stone here.
Ambo: Hope I'm not too late, but here are two pics for size reference. I didn't have a 20 oz soda can, but I hope this 12 oz can will do!
ax174: Of course. It's pretty similar to the original pattern, but here's what I did:
First, make a magic yarn loop
R1: 4sc into the loop, pull the end to tighten, ch1, turn
R2: 2sc in each sc across [8 sts total], ch1, turn
R3: *2sc in first sc, 3sc* twice [10 sts total], ch1, turn
R4: *2sc in first sc, 4sc* twice [12 sts total], ch1, turn
*for the green amineko, I stopped after R4, so instead of ch1 and turning, I fastened off. I added an extra row for the pink amineko.
R5: *2sc in first sc, 5 sc* twice [14sts total], fasten off
Then I sort of used my fingers to pinch the tops of the ears to make the shape appear even more triangular, if that makes any sense at all.
Hope that helps. ^_^
