What does tacking textiles mean?
“Tacking” is when you roughly sew fabric together (after pinning) with a needle and, usually, one piece of thread to hold it into place before sewing it properly with a machine. This makes it more flexible and easier to handle. It’s usually practised by beginners as more experienced people tend to sew the fabric straight after pinning things into place as it’s quicker, but can be a bit fiddley sometimes.
