Why not put your washing pegs to another good use! Fridge magnets! Their so easy to decorate and your fridge door will appreciate the attention.
Buy strips of magnet from craft shops or eBay. You can buy it by the meter with one side sticky, the other magnet of course! Then cut up strips to match your peg length. Then on the other side use any stickers that take your fancy! I saw some stickers with phrases I could put on my pegs to help keep me organised. I’ll be able to peg my receipts, notes and keep them all in order! (Notice there are none yet in the photo!)
If you just want simple decor to maybe use to peg a few photos on your fridge door, why not use decorative washi tape.
