Has anyone noticed a change in Connecting Threads Thread? The last couple of spools received had knots, spurs and created much more lint in my machines both while piecing and machine quilting. This problem has developed in the last 6 mos. Several ladies in my quilting group have had the same problem and, combined, we buy a lot of thread from them. I was wondering if they have changed their supplier for the egyptian cotton thread? Can anyone recommend an alternative retailer on-line to buy exemplary thread at the same price?
