I always wind my own bobbins on the machine they will be used in. I find the Coats and Clark cotton wrapped poly to work well for me on all my projects. I use a cream color (I think the number is 8010) for all my projects. Haven't had any problem showing through, even on dark fabrics. I haven't had any lint issues either. Also, it's less expensive than some other name brand threads and you can find it on sale at JoAnn's and Hancocks for 50% off. That's when I buy a lot of spools.
