My 5 year old was playing with a 25' measuring tape and sprung the spring inside. Yes, he got scared and came running to mommy, but all I could think of was, Cool, now I do not have to go buy one for some Snap Bags that I want to make.
Just had to take it apart to roll up the tape measuring tape so that I do not have a pile in my sewing room. Now to get the scraps out and get sewing. To much fun for me....
