How to Measure for Your Pouch Sling & General Info to Compliment Your STBS Sewing Instructions
If this is the first sling you have sewn, I suggest allowing for a few extra inches of fabric beyond your measurement calculation, just in case you have a few minor sewing mishaps.  Completed pouches can be shortened quite easily (see our website) but if you make a pouch too short, you can't safely make it larger.
When taking your measurement, wear a form-fitting shirt that fits you well (like the one I'm wearing in the pictures above) and use the seams of the shirt as a guide when you measure.
Always wash and dry your fabric before-hand on a hot gentle cycle to preshrink it.  Linen in particular is famous for shrinking several inches.
If using a fabric with stretch, the stretch should run the width of the pouch.

The pouch below is too large: the baby rides too low on his mother's hip & the fit of the pouch is not snug.
Same pouch, same baby, but a different-sized babywearer.  Here, the pouch fit is quite good:  the baby rides just above the hip bone and the pouch fabric has enough tension to keep the baby in the pouch.

Measure from the ball of your shoulder, across your chest (like a sash) and end the measurement just above your hipbone.  The tape should be held loose enough to follow the contours of your body.
  How the Pouch Sling should fit:
A well-fitted pouch is worn cupping the ball of the shoulder and extending diagonally across the wearer's torso.  The baby's bottom is centered on the
curved seam of the pouch; the baby's weight pulls the pouch taught.  If worn on the hip, the baby's bottom should fall just on or above your hip bone.  If worn in a front carry, the baby's bottom will rest somewhere around your navel.  Without a baby in it, the pouch should fit rather snug but not so tight as to make you feel that you can't move, let alone get the baby in the sling.
This is the pouch that is used for the illustrations provided with your kit.
If your finished sling is too large, then you should not use it; a pouch that is too large is not safe because it will not be under tension.  It will also be uncomfortable to wear, usually pulling on your lower back muscles.  But don't worry!  You can take the sling in at the shoulder....see our website http://www.sweetthingsbabyslings.com/order_stock_pouch_resize.html
for full instructions.
If your finished sling is too small, then you should not use it; in fact, you probably won't even be able to get it on.  If you can get it on, you probably won't be able to get your baby into it.  And, if you do somehow get your baby into it, you will be miserably uncomfortable and your child may not be able to breath or move properly.  It is not a safe situation.
