I buy as many metal rulers (like an L shaped one) from the hardware section or a straight metal ruler from the office supply store. Helps when I straight cut fabrics. I line up the ruler and the lines on my cutting mat to make sure everything is all even and so easy to just run my to rotary cutter along the metal ruler. Also, have purchased from Wal-Mart, in the ktichen plastic area, a 9X13" type plastic cake carrying pan. It has blue handles on top of it and my sister says it's the most wonderful thing to place her finished quilting blocks in so that they don't get wrinkled. She swears by it.
