This time around I have been cutting thicker plastic strips. When crocheting the squares, I used 2.5 cm strips and found there is less stretch in the finished work. The white handles were made using 4 cm strips which felt a bit cumbersome to work with but have provided what feels like very substantive and strong handles. The crocheted handles on previous bags have stretched when holding a significant weight. I'm hoping these new handles will stay intact regardless of the weight in the bag.
