I have always been a pins and scissors girl, now and then even laboriously transferring the bought pattern to 'butchers' paper (like unprinted newspaper) then using that to pin and cut.
I am wondering whether to go for a different method, like using weights to hold the pattern down (tins?), dressmakers carbon paper and a notched wheel to trace the pattern onto the fabric and a rotary blade and cutting mat to actually do the cutting.
I always use a rotary cutter. It's fab for difficult fabrics. But you need a big cutting board - for adult trousers, say, there is too much moving the pattern around to get an accurate cut. I mostly make children's clothes and it's perfect for that.
I always use weights. We live near a beach and the dds have picked up pretty flat pebbles for me - lots of different sizes and weights. I cut my own patterns mostly so nothing is on tissue appear and the pebbles work better with the thicker paper. Once weighted I draw round with a chalk pencil. Then use carbon and a tracing wheel to mark darts etc.
Tailors shears for cutting as I can't get on with a rotary cutter.
Varies depending on the fabric, but I always weight rather than pin. Usually weight with my quilting ruler and rotary cut - possibly because I generally use pdf patterns that I've printed, taped and cut myself.
Occasionally I use water soluble marker to draw round the pattern if it's very fiddly, then use shears to cut.
