I use a small plastic container to hold my bobbins. I wind about 20 at a time put them back in the container and go until they are all used and then wind again. I clean my machine after every 3 bobbins. I hate looking in the machine and seeing bunch of lint. I have an attachment for my vacuum cleaner to suck out the lint. Love that tool and another one for my other vacuum to clean out the computers dust. Living on a farm means lots of dust so this is a valuable tool.
