By: MBHayes503 Re: foundations using paper - hints A few hints on foundation piecing with regular office paper. 1. Make sure you use a small stitch. 18-20 stitches per inch or 1.2-1.8 mm. Some people recommend a bigger needle (size 14 or 90), but I find this is not neccessary. 2. After you stitch each seam, CREASE the paper. Fold the paper along the seam line that you just stitched. This simple step weakens the paper and makes it easier to remove. (Remember how you crease a piece of paper if you want to tear a straight line? - same principle at work here) 3. When you remove the paper, hold the seam with your fingers and remove the paper directly opposite your fingers. Inch up the seam in this way and you should never be in the situation where you are tugging on an unsupported seam. You are always stabilizing the seam with your fingers. I stabilize with my left hand and rip with my right hand. 4. DO NOT remove the paper until you have all sides sewn. This means you do all of your sashing or border before you remove the paper. It is hard to leave that paper on until the blocks are set. However, if you do this, you will have perfect blocks! I prefer paper piecing for machine work as muslin foundation shrink slightly. Another advantage of paper is you never have to worry about the stretch of the foundation fabric.
