I got so frustrated Saturday watching Fon's and Porters show. one sewed while the other handed triangles to be sewn into hst's. the lady sewing stopped sewing well before the end point and placed another set of triangles near it and kept on sewing. luckily their machine didn't make the fabric move to one side or the other. lucky!! i hold onto mine till it is in the end and then needle down before i put more in front to be stitched.
Each to her own!
