Recently I was fortunate to make a US-approved People to People trip to Cuba. We were in two large cities, and of course I was interested in finding out whether anyone there knits.
The short answer is NO. There is some crochet, but mostly I saw beautiful hand embroidery:
I believe that yarn is inaccessible to the people there, and since it is quite warm, there is not much desire for knitted items in other than lightweight cottons.
Based on the tools that I saw in the fields — primitive by our standards — if knitting were in practice, one assumes it would be accomplished on hand-carved needles. I’m curious to find out, however, if other knitters know differently. If so, please share with us!
