sorry for the delay. I totally missed the notification for this question 🙁 ok, so you’re going to lay your fabric flat, single layer with the selvages at the top and bottom. Take the top with the selvage and fold it enough to fit piece 2 on the fold. Do the same to the bottom, folding enough to fit piece 1 on the fold. Now piece 3 looks kind of odd in this diagram but essentially you’re just cutting this piece once. In order to fit it on the fabric, one side would be under the flap of folded fabric at the top. If it were me, I’d fold the top, cut piece 2, then unfold the fabric and fit the other pieces on. Hope that helps and you can get started 🙂
