Crafty Crafty writes about this portico made from 'cycled 'brellas. "The team over at craft portal ReForm School created this giant sunshade almost entirely out of recycled brollies. The end result was achieved by simply sewing the edges of each umbrella together, then adding eyelets around the perimeter. It worked a treat during a party they were throwing for fellow crafters and lent a really festive look to the patio."
DIYable for sure, but I bet it'll take a bit to dial in the tension knob on the sewing machine.
