Cut the sleeves of the jumper / cardigan, and turn inside out!
Fit the sleeve to your foot like so and then...
Pin or chalk, if pinning leave a cm of room to get it off your foot.. (I got it stuck!)
Once it's off your foot, pin it properly (try and use these colourful, ball-end pins as the other thin metal kind become invisible!)
Second fitting 😀 (if its too tight anywhere, unpick and try again! No harm)
Cut off excess material, leave about cm spare, to stop the sock from unravelling! Turn right side out and...
REPEAT for the second sock and tada! 😃
Now decorate anyway you like by hand stitching any fabric decorations on! 😃💜
