Maggie's own design, this 19 page tutorial is an advanced level upcycling coffee bag tote construction tutorial, The finished size is about 16" wide 13" tall sides and 5" deep but is adjustable. There are two handles, which are fabric straps. The inside layer is the silver espresso bags from Starbucks and the outside layer is bags from many different roasts of Starbucks coffees selected and designed to appeal to the artful eye. Use any coffee bag or other bags made from same type of foil-plastic laminated material, or you can use textiles in cotton or other materials.
The difference between coffee bags and fabric is that the coffee bags do not ravel and no turning for seams with the coffee bag material, so adjustments would need to be made if substituting fabric for coffee bags.
I enjoy giving a new life to items that have outlived their usefulness; such as feedbags and coffee bags upcycled into totes; make broom handles into looms then weave rags into rugs? Follow Maggie's blog at http://maggiescornerdotorg.wordpress.com/
