Forty-Two Miles of Thread

Yes, you read that correctly. 42 miles.
I got this free at Saturday's Project Linus blanket event. A stand is being made for a mere $3 so I can use it. 100 of these spools were donated by a P&G mill which actually makes feminine monthly products (you can guess what the string may be actually used for!). If the stand and thread work, I may truly NEVER have to buy white piecing thread EVER AGAIN!
