I rummaged through my collection of recyclables and found a cigar box. My daughter suggested that I paint it white, but I thought there was a nice old wooden feel to it.
To insert shelves, I used craft sticks as runners.
I cut the shelves from my indispensable venetian blinds. In the middle of each shelf, I glued small craft sticks (of the kind that pretend to be matches). Then I put in diagonal shelves. I didn't even have to glue them.
When I put in yarn, colour-sorted, it looked very natural. It is embroidery yarn which my daughter showed me how to twist, just as they do with wool skeins. I then used the original paper bands to wrap around small balls which I made from loose yarn and wool threads.The knitting needles are toothpicks.
