I have read alot of posts about threads in top and bottom and how people like them. I have a midarm megaquilter on a frame and would like to see what people with these machines on a frame use. Do you use the same thread on top as bottom? King Tut is 40 wt, use the same on bottom? Any input would be great as I am going to be ordering some thread to start experimenting. I like to see the thread on the quilt, but I dont want to see any bobbin thread loops on top either.
