So after a few days in the open, thread a large needle with at least 2 strands of embroidery floss. I used yellow in the same color. Now that I think about it, it might be fun to try it with fishing line so they look like they are floating in the air - maybe next year! Push the needle through both ears and pull the thread until about 12 inches from the end. This is your allowance for hanging to garland.
These things drop A LOT of sugar. I mean A LOT! If you can work on this outside, do. If you can't, try to work over a tray or something.
This is not the craft for you if you can't deal with sticky fingers. You will be a gooey mess.
This is harder than it looks, especially the knotting part. The first few are OK, but as your hands get stickier and the string gets stickier from multiple passes through the bunny innards, the string starts to get tanglier and your hands get clumsier and it can get frustrating. You may want to do several shorter strands and just tie them together.
