That's adorable
How did you make it? Did you knit the little jumper the monkey has?
I sewed it. Both her costume and the monkey's costume were made of polar fleece, which has some stretch across the grain.
I covered a button with fleece for the monkey's belt buckle. I sewed the belt as a waist band for his shorts and left openings for his ears in the sides of his little hat and his tail in the back of his shorts. The antenna was a straw from a juice box with a round bead glued on top.
I made my daughter's WordGirl costume as leggings and a long-sleeved shirt rather than making it as one piece, so it would be more comfortable to wear.
I bought a round metal belt buckle at the fabric store and covered it with yellow fleece and made her belt out of tangerine fleece. I made the cape out of yellow fleece and lined it with tangerine fleece. I made a hat for her. I even made fleece spats to cover her snow boots we bought in London. I tried making gloves to match the spats but they didn't turn out well, so I just bought red knit gloves for her to wear.
