What you will need:
ribbon or cording
Trim your threads again and cut 2 small slits right next to each other, through one layer of tulle on the top hem you just created. This is so you can thread a ribbon or cording through and cinch it up so that none of your fruits and vegi's fall out.
Next heat the ends of your ribbon or cording using a lighter or match just until they begin to melt a little, this will keep the ends from fraying.
