I think gpiew has ordered some and I will pm her to ask what it is like. Thanks for the expressions of interest, everyone. I will cost a 50 yard bulk buy and see whether it is feasible. I will have to add on a margin for the rescues, of course, but I expect it will be cheaper than buying a small amount and having it shipped from the States as one or two yards.
I am also thinking of buying a pack of ten inco pads and making custom fleece-covered cage pads if anyone is interested. They would be 95cm by 95cm. I have yet to cost them fully, but they would be selling them for about £22-25 (with patterened fleece sewn on) including postage.
I am planning to upgrade my website to one where you can display 30 products so that I can increase the range of things I am making.
