I love the Alpha Stamps site for all the variety of craft goods they sell — rubber stamps, gifts/cards, gift wrap, collage supplies, and their really beautiful collage sheets (check out the art deco ones). The Vintage Sewing Kit ($19.95) is one of my favorites for all the vintage images, buttons, antique measuring tapes, and more. The site also does a great job at helping you get inspired showcasing some examples of book covers and blank books created with this kit. Pictured here on the right is a finished book cover by Bella Ayers. Link.
