For the record, I love all the market bag/totes I make - however, we are allowed to have a favorite and this is it!!!
My Eco-Friendly Grab and Go Plarn (plastic yarn) Bag: http://www.etsy.com/view_listing.php?listing_id=29520417 was put to the durability and user-friendly test and it passed with flying colors.
My husband and I recently made a trip to Canada for a family visit. I used this bag to hold my crochet stuff I took to keep me busy on the plane and during the lay overs in additional to other stuff I put in it.
The straps made pulling stuff out and putting stuff in so easy. Above all it lived up to it's name of 'Grab and Go' because all I had to do was pull the long strap thru the small strap then over my shoulder it went and I was off.
