I made a Hab type wrap as did another BB member using a soft, stretch knit, very similar to what the HAB is made of. We doubled up the section that bub sits in by about 50 cms and quadruple stitched - worked beautifully for DS and then got passed on to my SIL for her DS and now DD. Will see if I can find the instructions we used to make it - cost us about $30 and the edges didn't need to be hemmed because of the fabric we used. xox
