I want to try prewound bobbins on my Tin Lizzie because my bobbin winder has been cranky lately (only fills the bobbin half way). I've looked around the net and prices are high and many prewounds have cardbord sides or maybe no sides. This doesn't seem right somehow. Have you used any of these? How about plastic sided prewounds, are they better? What is the deal with magnetic prewounds, how does that work?
What is the best kind? Where is a good place to buy? Please share your experiance. Mary
