These markers are the best! I bought them for my teenager to make a T-shirt for a book-release party. As she was using them, I thought, these would be a great rainy-day activity! I take care of two children a few days a week besides my own, and immediately decided to try it.
These markers are so easy to use, I was easily able to give them to the children, ages 5 and 7, and let them go to town. (I had dragged out a white sheet for this particular project, which they would later use a a fort!) Once they had decorated the sheet how they liked, I let it dry overnight, then ironed it next morning, and voila- instant fort!
Part of what I like best about these markers is that although they carry warnings of being permanent, I was easily able to wipe any accidents right off the table with ordinary household cleaner. I did take the kids' shirts off during the project, just in case.
So if you're looking for a cheap and easy craft for kids, this is definitely a great way to go!!
