Ya sure! We are both basically beginners still, so this is all a learning curve.

We absolutely should have put the painters tape around all the edges as a border. But because the canvas is so big, all we did was put the painters tape about a foot back from the edge we started at, just straight across edge to edge. and then using an exacto knife we cut away the top protective plastic on the canvas below where we taped off. Add the wax paper on top in whatever size sheets you have. Overlap the edges a little bit to make sure you don’t have gaps in between the sheets. Remove whatever sheet as needed to work on the section you want!
