I'd love some tips! I started making one a few weeks ago for my dd's birthday party this saturday. I made it, decorated it with my dd, and stuffed it veeery full of some small toys, stickers, and a lot of candy

its.. er.. kinda heavy. I'm starting to worry that I maybe made it too heavy! I poked two holes towards the top and strung some yarn through it, but the other day when I lifted it up to show someone, the yarn ripped out! I did 3 layers, but its possible that towards the top where the yarn went that I put it through a weak spot because thats near where I was leaving the hole in it. I was thinking of finding a spot that feels particularly strong (anywhere on it, not necessarily the top) and shoving a zip tie through it. Then filling it to the top with crumpled paper and then paper mache-ing over the hole at the top.. the crumpled paper would be to protect the goodies inside from getting starch dripped on them. then wherever the strong-feeling area that I put the zip tie through would become the new top. Does this sound good? hoping its not too heavy...
