I can't wait to paint on these formats

I can't wait to paint  on these formats - student project

I made several mini formats. I made some of them from white paer and some from black paper. I actually made them and found that they were much smaller than I had imagined.
Using 1cm wide washi-tapes, I was able to frame Formats 1 and 2 easier. I can't wait to paint on these formats.If I leave them for a while, I am a little worried that the washi-tapes will not come off.
