The throat space will help you greatly. You just scrunch it and sew. I suppose you're not doing free motion on the 201 and are doing stitch in the ditch. A walking foot would help you not get puckers, but if you don't have one give it a try without to see how each machine does. You should try to stitch from the middle first and then outward. You also want to change directions so you're not always sewing the same direction. This can cause distortion and the dreaded puckers. Be sure your backing is taunt but not stretched and that you top is smooth and pinned every 4-6 inches and you'll be ready to give it a go.
