This is interesting because I was looking into buying some also. Like you said, it is an investment. I thought about doing something with it a kid's t-shirt.

I am also interested, but would definitely like to know what others have thought before buying. It would be great for kids.

No but I look forward to getting some it looks interesting

I'm afraid not. *

I haven't tried the solar active BUT I did try glow-in-the-dark for some stars on a black sweatshirt...turned out pretty good!

Back to the top. I'm interested also.

I have not used it (YET). But, was at my sewing machine dealer yesterday and ask them about it. This is a "Mom & Pop" type of store. She said it sews great, she had some in the store so I took it outside to watch it change. Kool!! Just not sure what I would sew it on right now. Good luck. Sue *4U & all

Yes - i have the full set of this thread. It stitched out great. We had a family trip to Hawaii, and I did each Grand a shirt with something typically Florida. And, when they went out into the sun it changed colors. They thought that it was very cool, only thing - the older GS didn't particularly like the pastels. I purchased a spool at our Viking center, but was expensive. Bought the entire set on Shopper's Rule. Quite a savings there. I had to mark each spool to know what color it changed to so that I could not get confused.

Thank you for the information and interest my cute friends!

Not yet, but I also checked with the local embroidery store and they have it, so I do plan on trying it.

There were questions regarding these threads. The sets that I have are called Fun-n_Sun. 6 of this set all appears to be white, but changes to yellow, apricot, green, lavender, periwinkle, and orange. The other 4 are colored. Sky Blue turns purple, yellow to orange, pink to magenta, and peach to pink. They are not marked, but only have a number. Of course, I kept these separate from my other threads, and keep a "cheat card" with them so that I can keep them separate. But, they are neat to stitch out. The white gives the tone on tone until out in the sun. I had a sewing friend that stitched flowers on her wedding dress with the white threads. Her reception was held outside, and the Florida sun did wonders with that dress. I hope that maybe this helped answer some of the questions.
