I've made a crap load of shopping bags over the years but these are my favourite. They are super heavy duty as the outer fabric is a thick corduroy. They're fully lined and the straps are reinforced with 3 rows of stitching making them super tough.
Oh yeah, also advertised the whole vegan thing as they are used for grocery shopping. Get tired of answering questions when people see us buying bananas by the boxful, etc. The vegan labels explain it all.
