First turn your socks, inside out. Lay your inside out socks, out on your work surface. Have one with the heel in the center and folded down toward the sock opening. The other with the heel folded out (like a traditional Christmas stocking).
Here is a drawing (I am still learning how to use the computer program) of the two socks. The red lines show where you want to draw the lines on the inside of your socks.
So here is the sock that will be the monkey main body and legs. Draw a line from the top of the sock to just below where the fold down of the heel is.
On the other sock, draw a line from just below the heel to the end of the opening, draw another line over by the other edge of the sock from the opening to just below the toe. You don’t need to draw a line around the heel, just be aware that this heel will be the monkeys muzzle/mouth and you won’t sew it down, just cut it out and hand sew it where you need it to be. Draw the two ears, as is indicated by the elongated half circles. My Daughter-in-Law indicated that the ears were constantly being changed as she developed the best way to make these monkeys. These are how we made them this time.
