Another company that I've been buying a lot from lately is Clear and Simple Stamps. Their excellent quality and style of stamps keeps me going back to them. They have a series called "Ragdoll" that has dolls, props and scenery. They rival PTI in everything but customer service and Clear and Simple Stamps kicks their butt in that. My last order contained a free copy of PaperCrafts Holiday Cards & More, volume 7. It's 162 pages of ideas for cards, gifts and decorating and retails for $14.99. In smaller orders I've received large packages of buttons as a thank you.
I'm going to make my Christmas cards this year in exactly the same way - using different stamps, of course. If you haven't tried Clear and Simple Stamps, check them out. I think you'll be really happy with them.
