The version shown in the first photo is available in Fuzzy Knits. This includes the intarsia face and new ears. The t-shirt pattern is much the same as before, and the pattern now includes the super-cape as well.

The panda is knit from worsted weight yarn on 4 mm needles, about 15 g of each colour. The t-shirt is knit from 15 g of fingering weight yarn on 3.25 mm needles. All pieces are knit flat, then seamed and assembled.

The other photos show the original version of the panda pattern, which is no longer available.
