I use the blue painters tape a lot. I use the original 3m brand. I use the wider 2" size to hold down my cutting mats (on the under side) and I use the 1" size to mark my sewing table to keep my seams straight. I also use the 3m blue painters 1/4" tape to mark my rulers when I'm cutting fabric so that I don't have to keep checking to make sure I'm cutting with the right measurement.
I don't use it on my fabric though, never have as I use quilting rulers instead
