This is a lovely little project for adults and kids.
You need a square of felt as the base, some wool tops, a fine needle and a needle felt pad/foam base).
I used a white 9″x9″ 30% wool piece of felt as the base that I put through the washing machine first. This gives it a nice thick bobbly texture that is great for needle felting on to.
Make sure you know where your washing machine filter is before you do this as the felt can clog up the machine.
Pull off some clumps of needle felt wool and lay them out on the felt base in a rainbow pattern.
Then using a fine needle, felt the layers on to the felt square (watch younger kids as the needle is sharp) until the felt can’t pull off easily by rubbing it.
You can blend the joins by thinning out the felt where it overlaps each colour, or pull out fine strips to create tendrils.
