I use a magnetic board to hold my pattern instruction sheet while I sew. The instructions are then visible and don't get lost under fabric or pattern pieces. My sewing table doesn't face a wall, otherwise I would just pin the instructions to the wall (or better yet, a strip of cork adhered to the wall).
The boards are made by Lo Ran and are usually sold in the needlework section of craft stores. They're intended to hold the pattern sheets for cross stitch or needlepoint but I don't see why they don't market them to sewers too! The beige boards come in many sizes and sit on a folding plastic easel. The one I bought came with the easel and a couple of magnetic strips.
