I find on my Viking machines that I have to slow down the bobbin winder even with regular threads as they wind so fast and so tight it causes the bobbin to cling to the winding post and I've had to unwind several to get the bobbin off and to toss as it distorts them. I seldom use clear threads but may do so on applique on wall hangings.
