My 'design wall' is a Design Layout Sheet made by Clover. It's 58" x 60". I can hang it over my shelves when I want to preview a design. Fabrics cling to the sheet and don't need pinning, and you can even fold the sheet up with the designs still on it (there is a protective cover sheet included in the pack). It's a great product, but not very cheap - £18.75!
