Berny, know that dilemma well. When I go to my groups I always take enough for a week when I only go for a day. :-)
Surprised myself on my last group night - I only took ONE project. And it worked well!
Try to pick something that you can complete in your time at Blackpool. And then take a second project for when it is finished or something goes wrong with it.
At least that is how I try to work my special days out. :-)
I am very naughty, I take crocheting to sewing days and sewing to embroidery days. But mostly I have FUN!!!!
Have lots of fun at Blackpool.
Well, it know it is hard to choose...but error on the side of too much...when I don't, I usually have to go buy it when I am there...borrow it, or do without...
Have a wonderful time. And better too much than too little.
Enjoy Blackpool, its years since I visited. My grandparents lived in Lytham so we went frequently. Happy sewing
