I have been looking at many pictures of string quilts, and would like to try one. I don't really understand what to do after cutting the strips. I seen where we are suppose to have a square foundation to sew the strips too. They show using a piece of paper. It also looks like they sew the first strip in the middle of the square paper. Are these strips always machine sewed or can they be done by hand? I kept thinking I would like to sew some strips together while sitting relaxing by hand, but not sure that is done. I just don't yet have all the instructions where I completely understand the method. Can anyone give me some information to help my understanding?
