Today I made a tiny sock monkey! I went for t-shirt materials that look like the same colors in a sock monkey, and just went to town! I tried to keep similar construction, too, to add to the look! T-shirt materials, if you don't sew them too tightly, remain loose and can fray a little to give the appearance of a knit. I used seed beads for the eyes and less than one cotton ball to fill it.
I think this little fellow is a tad too large for the house, but they make oversized sock monkeys too, so it can work.
