So here's a picture of me at the con. (somebody else posted it online)
Tips I learned:
- don't hot glue anything that can be pulled/stepped on
- snaps only work if you can set them properly
- bring hot glue for repairs (i thought of that beforehand and was glad I did)
- ice packs are wonderful things
But really. Sew or permanently attach everything you possibly can. It's a pain to do it in the first place, but TRUST ME, it pays off in a hurry
