Hi Jackie
#1....I've never used a maker so I really can't comment on them.
#2....When I'm attaching the yo-yo's next to each other(as in the picture), I try to get the more flat edges next to each other. When you look at a yo-yo from the back, you will see some points and flat spots. Does that make sense?
#3....I have raw edges on mine. To minimize that, gather closer to the raw edge...but don't let it fray. This takes a little practice.
#4....I pull the thread as tight as I can and put my finger right next to the last stitch I made and tie a knot or two.
Good luck and looking forward to seeing it!!!
