A trio of monkeys.

Take a pair of unworn socks, turn inside out

Divide the sock in half put pins to mark this line to about 1/4 inch from heel

sew along ribbed edge and up one side of pins, repeat for other side.
Remove pins and cut along this line to make legs.

Turn right way out and stuff firmly through "Crotch", Sew to close

With other sock cut out heel section, hem if necessary.This will form mouth

Stitch in position and stuff firmly, sew to close

Use leg part of 2nd sock to make arms and tail

Stuff and sew in place

Cut ear shape from matching felt and sew on to right side of sock
Trim and turn inside out

Nearly there, position ears and sew on

Add buttons or felt eyes.

Voila your monkey is complete.
