Hi - have never tried knitting on circular nedles before and about to start my first project. It's a chunky knit snood using circular needles. However..I have ordered 80cm long needles and the pattern calls for 60cm. I'm on a really tight budget so can't afford to spend money on returning them and getting more posted out and haven't seen ones the size I need (9mm x 60cm) on the usual sites I use. Is there any way I can still use them or do I need to go back to the drawing board?
