About a year ago I was in desperate need of a new cricut mat but did not want to spend money on a new one. I started researching and found that I could use the same cricut mat repeatedly if I bought Aleene's tack-it over and over glue, a sponge brush and a small jar. The steps area really easy and this hardly takes and time at all.
Gather your supplies.
Mix equal parts of glue and water.
Brush the mixture over the whole mat.
Let the mat dry over night.
When the mat is dry pat your hands over the entire mat, if you don't the mat will be to sticky!!
Make sure to seal the jar tight so you can use the left over mixture next time. Also rinse the brush really well. I hope this was helpful! Spoil yourself with the money you saved. :D
