My thanks to Jan Andrea
for the inspiration and guidance on how to make this. I had some issues following her directions, so I decided to post what I made here (with my alterations). My hopes are that my struggles won't be yours.
Again: you can find the original instructions at Jan Andrea's webpage
Interesting note: The curved-seam pouch was invented by Hygenia Halfmoon, who then showed the method to Nancy Main, who started "New Native". Now many pouches for sale are labled "Native-style" even though they are a very recent innovation (certainly not actually Native American), dating back to the 1970s with Hygenia's book "Primal Mothering in a Modern World".
Thanks again to Jan Andrea for this tidbit.
A pouch-style sling should be between 20-22" wide before it's folded for wearing and 10-11" deep when folded.
Visit Hotslings.com for great wearing directions, until I make an Instructable on baby wearing.
Fabric: Between 1.5 and 2 yards of fabric depending on the size; he most you will need is 2 yards, unless you are built very large.
Sewing machine and thread to match/contrast with the fabric.
Time: under 1 hour, even if this is your first project.
