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.
Step 1: Step 1 : Get your measurement
Measure yourself from your shoulder to the opposite hip (the point of your shoulder, and the place on your hip where you rest your hand if you place your hand on your hip -- this number will probably be somewhere between 20 and 30"). Double that measurement.
Add 6 inches to your doubled measurement. This is to make room for your baby. So your final measurement will be somewhere between 46-66”.
I am making this one for a friend and her shoulder-to-hip measurement was 28.5". We are going to round up to 29" to make it easier. When you double 29" you get 58" then add 6" for the baby to get a total of 64". This is the final measurement for the length.
