Hello all! Anyone know where I could get something like a foam tubing or similar that could be used as a large piping insertion? I need to wrap fabric around a "sausage" of foam to create a raised edging like an over sized piping cord?! About 2.5cms diameter across would be perfect, but I'll take what I can get!! Should be foam and squashable, rather then stiff and would 'crack' or bend.... Any ideas??
