Hi, I am wanting to try this invisible thread on a quilt I am making. Does Joann's sell it? Can you use the invisifil thread for the top thread, and another color for bobbin thread? I tried using some clear thread I had, and it is so thin, keeps breaking all the time. It is some I've had for awhile. Do you have to set the tension different when using this type of thread? Sure would appreciated any impute on this. Thanks so much.
