This is a very detailed pattern with a great supply buying guide at the beginning. I did have to mail-order a few supplies, like high-density foam for the hip support and all of the heavy-duty fasteners, but the pattern includes sources for the special materials. I would encourage anyone who needs a baby carrier to try sewing your own with this pattern. It seems complicated, with the nap hood (which zips in its own integral pouch) and all of the adjustable straps, but it was much easier to complete than I thought it would be. Totally do-able. The savings over similar store-bought carriers was substantial and the SweetPod is way cuter and much more comfortable than some carriers that don't include the hip support.
I'll be using it again this afternoon, on a trip to the nature center. Happy hiking (and sewing).
