Etsy Labs posted a fused plastic bags tutorial back in May. Since we suddenly have an excess of plastic bags (I am trying to bring my own bags to the grocery store now) I thought I'd try out the tutorial. I started out with 8 plastic Target bags and cut off the handles and the bottom seam.I then cut them open so they lay flat across the ironing board (ink side in). I covered the plastic with a piece of interfacing and ironed the sheets together for about 20 minutes till they fused together and became one sheet.
I then cut that sheet up and sewed a fabulous lunchbag large enough to hold the square Ziploc containers I use to store all our leftovers. Makes packing lunch in the morning a breeze.
