Whilst I was 'out and about' I had to have something to pick up when I had some spare time.
I never tat on the plane as I'm always afraid of dropping something and then not being able to find it again on the floor. Plane seats seem to get narrower and narrower and more and more squashed in so tatting is, for me, a no, no. BUT there are always the departure lounges where the light is pretty good and there is always plenty of time to sit and tie knots!!!
I pre-wound Ez-bobs with either size 40 thread or HWT. I put the chain thread on first and loaded the beads onto that. That was followed by the shuttle thread. I found I could get two 'projects' onto one Ez-bob. Here are two that I made on the trip (or just before!).
