I was sewing with a dear friend every Sunday evening - we were taking a beginner quilting class and did our homework together. We tried continuing that after the class was over, but I was the one loading up my machine, etc and bring it over and that got old. Biggest problem was when I got back to my house I didn't unpack it for a couple of days each week and missed out on prime sewing time. I try to do a little bit each day after work.
So we've decided to get together when we have a sandwich to make. Neither of us likes to do that so doing it together should help. I have three tops waiting for this. She has a new grandboy who is taking up her time right now! But ... we'll have a sandwich marathon soon.
When we're together we are very intent on our own projects - and sew for 3 - 4 hours. So no problem with getting the job done, just life and having to pack it slowed us down.
