This is so simple.
Take a bamboo dishcloth bought from the supermarket.
It has huge holes...
Use cotton knitting yarn, we use a rainbow one,
and a huge needle. The holes are so big you can use plastic kids sewing needles,
but we use an upholstery type needle as shown below on the right.
Big Seed went up and down wherever he fancied.
That's brightened my washing up!
