I just use the first two or three rows of any doily pattern and add 1-3 rows of chain stitch netting. I finish off and start another, joining on the final chain stitch row to the other half.
Then I dilute some Modge Podge with a little water and apply it to the crochet with my thumb and fingers. Insert a small round balloon, blow it up and let them dry on wax paper.
It's a very versatile project. The ribbons can easily by removed, or changed to different colors as the seasons change. And of course, you can use different color threads, or make them as big or as small as you want. You can see the different sizes that I ended up with, just by changing out double crochet for half-double, and by changing the number of stitches in the crochet chains.
