Grid paper has been affixed to the cardstock mesh sheet! It's looking pretty good. All I need now is some paper tape to get the gaps and edges protected.
I did get things a little uneven on the bottom where the thin strips went and the liquid glue I used was a little too effective so it's a bit bumpy around the edges too but altogether, I think I've done a pretty good job so far as someone who doesn't do crafts at all.
And it's only taken me 10 hours xD probably another 1 or 2 with the paper tape when I get it.
