Aside from the bottle with sponge tip you'll be needing paint also, I have left over poster paint that was use during the children ministry activity on our church. It is a washable poster paint that is perfect for toddlers.
Mix it up and pour back the solution on the glue bottle, screw back the sponge tip applicator, do the same with the other colors and your DIY Dot Markers are now ready to use.
My Li'l Lady Bug immediately tested it with the printable Do-A-Dot worksheets we found from these generous sites.

I think the consistency was still runny that if you will hold it in an upside down position for a long time the solution is coming out of the sponge tip even without squeezing it. So I'm thinking of either changing the solution's recipe or do something with the sponge tip. If you have other ideas regarding this, please comment away. I'd love to hear from you.
