Who says a stylish handbag or beach tote has to come at a high price? Plastic bags are often turned into, well, more refined plastic bags by the hands of knitting and crocheting enthusiasts. Proving that one man's trash is another's treasure, crocheted bags can be made from old plastic bags that have been cut into thin strips. On a similar note, plain old wool yarn takes a back seat to plastic yarn, or plarn, which serious knitters use to create a more polished product. Recycled craftswoman Helle Jorgensen advises that it takes a long time to weave plarn, but it yields a unique finished product [source: Gooseflesh]. If the idea of making a bag from a bag sounds too redundant for your taste, plarn is also handy for weaving potholders, dish scrubbers and doormats.
