What things, specifically? If you're making cards, that's the Papercrafts side, if you're scrapping, that's the Creating Keepsakes side. Most of the materials I get are from a local scrap store (lss) or Michael's or Jo Ann Fabric. They have great paper and stickers and tools and embellishments for scrapping and card making.
Hiya, btw (by the way). Welcome to the board! I usually don't post down here, I do the NSBR (non scrapbook related) or CK. I visit the other boards, but don't usually post there.
