Need to build a furry creature ...or some other three dimensional costume? Consider using either German plastic bones from Farthingales or these super easy to sew through woven bones...remember Rigelene well these are as easy to use but there are caps for the cut ends so no prickly bits to deal with.
Love. Could easily be layered over other costume pieces [ADHNote: I don't like dangly things between the legs, bulky and sometimes impractical for simple walking if not designed perfectly. Change hem style to leg-points instead and wear loose cloth pants.]
