I’ve never used a Burda pattern before (have used many others, though), and I can’t figure out what the symbols for required notions mean. I’m making the Wiesn Dirndl and I don’t know if I’m supposed to buy elastic, lace, bias tape…there are these symbols but I don’t know what they mean! Is there anywhere on the website where this is explained? I feel like I’ve looked everywhere and I’m about to throw my laptop out the window out of frustration! Help PLEASE! I will be so happy if there is an obvious answer out there—I don’t care how stupid I look at this point. Thank you!
