I use regular copy paper too, set my stitch length to 1.8 and it works very well :wink:
If you print out a extra copy of the foundation, and cut out the pieces of the ones with angles, turn them over(non printed side) and use them as templates laying them on the right side of the fabric. Add 3/8 seam allowance and cut them out, you will have perfect pieces and very little wasted fabric :D:D:D
I hope that you decide to give this a try, PP is very easy once you get the idea that your piece is being created on the back side of the paper, and you are sewing the seams on the front... start out with a very simple block, some scrap fabric and have fun :D:D:D
