I bought the set mainly because of Rufflers. For this purpose, yet one needs additionally the Nähfussverlängerung no. 77 of Bernina in the Bernina 330. Works great, I'm thrilled. Ruffelt every time, on every 6th and every 12th stitch and additionally in various pleat depths by adjusting the orange. Will save a lot of work in ruffles! The other presser feet fit well and are convenient. The adapter I do not need, but the set has already paid off!
