I like how the tissue balls are hung together like this. I am not sure where you would do this in a tent though.
Everybody keep an eye out for some super cheap frames like these from flea markets etc. They might have crappy paintings in them that would appal me, don’t worry we can take them out easily. The people in this photo used the frames for their seating cards at the reception. I think they possibly could be hung up around the tent as decoration too.
Using cupcake liners for decoration seems cheap.. You can dye the doilies whatever colour instead of beige too.
