I know these quilts are not strictly clothing, but you can wear them on your lap or round your legs.
These quilts will add a bit of colour to your bed during the daytime as well as keeping you warm at night. They could also be used on your lap and around your legs if you want to sit out on cooler evenings.
If you would like a similar design with colours to suit your boat, then let me know. The price would be the same but there would be a few weeks wait while the quilt was made.
