Brief instructions for her "berry apron," - hilarious looking, but it would keep your berries from getting mushed. Looks like she is using it for coffee berries, but I could see it for blueberries too.
Cost of shipping a dimensional object wide makes this something to make on site. A roll bender, 2 steel pipe and 6 pvc pipe are the main materials. The larger the diameter the higher the yield in the area.
