I went to Peterborough for a bit of Christmas shopping last weekend and, of course, visited some craft shops whilst I was there!
Colemans stationers have a shop in Peterborough city centre and they have a decent selection of crafting items including docrafts ranges, painting products, rubber stamps etc. Worth a look if you're there but not really worth a special journey.
I then went to visit the Sir Stampalot store which is located out of the city in the Werrington business park area. I have visited the store quite a few times but recently have been disappointed by the stock they have. It almost looks like the shop is not actually open when you visit, but if you buzz, they will let you in. I have bought from their website before and have received very good service so, if I was you, I'd spend my time browsing their website and ordering that way rather than making a special visit to the shop.
I also went to Hobbycraft that has recently opened at the Peterborough Garden Park, just outside the city. It is a large store and has a good selection of different crafting products, as Hobbycrafts do. There were no particular bargains there this time but when I visited after Christmas last year, I managed to pick up beautiful bright coloured A4 envelopes for 10p each of 15 for £1 which was a pretty amazing bargain, so I will definitely be visiting again after the weekend!!!
