I was sorting through some old photos I did for my Garment Construction course last year and thought I'd share. There'll be a few of these sorts of posts appearing over the next few weeks covering different hemming techniques (Sarah!), dart construction, hand stitches etc. Basically all the stuff I was taught as a beginner last year. I hope they'll be of use to someone...
Tailor Tacking is a technique used by dressmakers to transfer pattern markings from the tissue pattern, onto the fabric. The idea is to leave a temporary thread marker in place to mark construction details like darts, bust points, zip placements etc. Once the dressmaker has no further need for them, (ie they have constructed that part of the garment) they are simply pulled out and discarded.
To sew a tailor tack, pass the needle and thread (double thread) twice through the point you want to mark. Leave about a half inch long tail. Instead of pulling the stitch tight, leave it as a long loop (again,about a half inch), then cut the main length of thread to about a half inch. You'll end up with a loop in the middle, and a tail either side as in the picture below. That is a tailor tack. Pretty simple huh?
A note of caution: I had some of these fall out because I left them too short. Completely lost where my dart was meant to finish. But these are brilliant if you don't want to mark your fabric with chalk or other markers, as this doesn't always come out (as I also learnt from bitter experience on my very first project!)
