We still travel as a family and I do not have time to sew.
But when the kids were much younger 3 years in a row I stayed in a cottage with them for most of the month of June. Once they went to bed I sewed clothes for myself.
If I had time now, I would bring my little Singer Genie and piece quilting projects.
I always have a crochet or cross stitch project to work on. I used to work on them when dh was driving, but due to a shoulder injury he cannot drive the RV as much and I do most the driving. We used to split it 50/50.
At home I sew clothes for the family and quilts for special occasions. This year I will be making 2 baby quilts, a quilt for Mum's 80th birthday and one for my son's high school graduation.
