05: Patio project: grout tape

Here is a product I found at JoAnn's Etc. It is actual 1/4" grout tape made by a company called Plaid. This is what I had planned to use on the patio project to mask out the grout lines. I had considered 3M's blue painter's tape, however the smallest width I was able to locate was 3/4" wide, which would have made for a chunky mortar line.

I had purchased 4 rolls for my approximately 200 square feet design.
