I made my usual MMF yesterday morning and worked with it in the evening. I don't think I added enough powdered sugar because it was way softer than usual. I colored a small amount and added almost 1/4 cup of powdered sugar to it and tylose powder (wanting to make flowers) last night. And it is still soft after sitting for 8 hours. Usually I have to warm up my fondant but this stuff is soft like I've already done that.

Any tips as to how I can save this fondant so it is workable? Thank you for your help in advance!

I would just keep adding PS until it is workable. The color will make it softer too
