For tunics I like a nice medium weight linen. I’ve found the fabric from fabrics-store.com IL019 is perfect.
For this project I’m going to order 4 yards of cobalt blue IL019 linen.
The pattern I made for my husband requires 3 yards of 58-60 inch wide fabric (size L-XL tshirt). When he was bigger (5x t-shirt) I ordered fabric in 5 yard chunks.
