All bags made of 100% linen yarn REX, 50g / 1.08oz (150m / 164yd) in ball. Cotton yarn will work too. Two bags made in one strand only, five in two strands (or you may use thicker yarn).
Recommendations for the choice of yarn and crochet size can be found in the pattern description of each bag.
“White cloud” and “Summer cloud” bags are semicircular. “Snow peaks”, “White shell” and “Diamond wave” are shoulder bags. “Weaves” and “Romanesque” are totes. All of them are great as a beach or grocery bags.
