I just used it for the first time! Problem is I made too much! Can you keep the thickened mix in a baggie? Or should I just toss the rest. Next time I will know to only make half a batch of it. What are some of the other uses for color flow?
Don't store it in the bag, but it can be stored for a while. Also anything you make will last for a long time. You can always make some different colored hearts and use them at V-day. Or something for Thanksgiving or Christmas.
If it is still thick you could also probably pipe and dry some flowers using it.
