Had a go with dd during a visit to a folk museum over the holidays and I quite fancy giving it a try, but don't really know where to start.
The guy who was demonstrating was using half a dolly-peg as a tool and was just shoving the scraps through with that, but my mum (who remembers making them when she was little) says you have to secure the scraps with a loop. Is this the best way? What about the edges of the hessian - do I bind them, or just double them over and work the rows of scraps through two layers? What about the corners?
Have looked on the internet for techniques but didn't really have much joy, and I'm not sure of the best place to get the base material from (sacking not being something we get much of!).
