Maree Langley in Melbourne is a supplier of travel pillows, round segmented pillows, 9 block pillows, bobbin bags (for approx.48 pair), carry bags (to hold the round and square block pillows, and which have internal pockets for supplies and books), plus a “book” style bobbin holder, and some cases for crochet hooks.  All the styrene used in the round and square pillows is high density foam, laser cut for me at a factory in Melbourne so that they are accurate, and are always the right size.
