I really love the old labels on them. Some of the balls were a little more.. partial than others so I decided to rewind them and found a few old coupons inside of them.
I don't know how old some of these threads are but the offer was for patterns from the 40's to 60's, for 15 cents each. Somehow I doubt they're still good.
I put the smaller rewound amounts in a jar. The bigger ones are on a shelf in a basket. I can always use the excuse that they are for decoration until I can find the time and pattern for them!
