Tell me about it. I have the same problem with the wife.

Three suggestions:

1. Your local shop-fitters.

2. Your local plastics warehouse. If you've never been to one, you'd
be surprised what weird **** they keep in stock. They also usually have
a scraps bin that they're happy for you to plunder so, for the quantity
you need, you might get something free that you can adapt.

3. MFI or Ikea. Scrounge around the bargain corner - there might be
bits and pieces kicking around. Do Ikea have spares at customer
services? Ask at MFI. There might just be a bit kicking round from an
ex-display.
