Here is a tutorial showing how I cover the beads for the buds for my Little brown bird quilt. The silk ribbons I use are hand dyed so the buds (beads) then have a variance in colour. I buy these from south Africa as I live in Spain but I know these ribbons are available in America. The name to look for is Di Van Neikirk.
Here is my method. I do mine individually. It can be done by just doing one after another but that is more difficult.
Will tell you what the various pictures show as I have not finished posting pics.
