After pulling the yarn through my grape with a large pointy needle I cut the yarn at one end about an 1/8th to 1/4 of an inch and felted it in as a brown dot at the end. The other end I cut at about 3/4th of an inch and I wrapped it in a little brown wool and felted. I roll the stem along the edge of my work towel while felting. It also helps to roll it between your fingers. I cut the end when it was done.
I can't wait to make my next piece of fruit!
