I went into our local Wilko's today and they've got some good Xmas buys. I bought a lovely pack of 6 x 6 paper (36 sheets of their own brand) for 2.50 and there's some lovely designs in there. Yes I know I was buying packs for a pound at the NEC yesterday, but this was too nice not to buy
They also had some inexpensive but lovely quality gift tags that could easily find their way onto cards. I was particularly taken with a pack of sticky back stencils for a pound. Think there were either 5 or 6 in the pack (they're quite small - sort of a peel-off sheet size) and they're re-usable! I was impressed with the kind of selection they had. I should point out though that none of it was in the "craft" section of the store, but the Xmas section. If you didn't know you might miss it, so take a look. Hope you find something useful that you like.
