We don't full time, but I have taken sewing projects to do sometimes. We have a 40 ft fifth wheel and the kitchen has a counter that I can easily use a 24 x 36 cutting mat.
Apparently there are a lot of RV quilters, this summer at our manufacturers National Rally we are having a mini retreat and shop hop (Shipshewana IN area). I already have a full house of people wanting to sew at the retreat, wish we had a bigger space!
Also there is a great group on FB - RV Quilters
