Thanks all, don't buy them often but want them for my daughter's party on the weekend (and want to minimize how many shops I have to go to). I live in Hereford and whilst we have lots of supermarkets, they are all little ones so there's not a lot of choice.
Sains do, but in a pinch could you get the big ones and use acookie cutter to get a couple out of each roll. You could use the leftover bits to make breadcrumbs for a futurw meal?
I saw them in Tesco earlier, a load of them in a bag in the fresh bread section, bakers rolls I think they were called - looked like little crusty ones and looked really nice.
