My fingers are covered in blisters but I'm super happy with how this wreath for my sister and her husband turned out. Their last name obviously starts with a "B"!
I cut about 1 1/2 yards of burlap into 2x2 inch squares. I folded the corners together and secured with hot glue and then repeated with the other set of corners until a balloon was formed. This tutorial has nice pictures of how to fold each "bubble". I used pins but found they didn't stick in my straw wreath for very long so changed to hot glue. Don't know if I would do this again. Definitely a labor of love!
