Baby Carrier - Hot Sling & Ring Sling

I have been dabbling in making some simple baby carriers. I can sew, decently, so these are all pretty easy patterns to follow.

Here is one that is similar to a Hot Sling:

This is a discussion board that I thought had some helpful information for a beginner:

And here is a link for a ring sling pattern:

The background doesn't go with the text font very well, so its a little difficult to read, but good instructions.

Here is where I purchased my rings for the ring sling:

These rings are very affordable and quality rings - metal or acrylic

To give you an idea on cost, I paid $9 for my rings (but I accidentally bought two sets, so it would have been just under $5... only order ONE from slingrings.com - their wording is a tad confusing) and I had the fabric on hand. You need about 2 yards of fabric for the ring sling. It only requires being able to sew a straight line so its pretty easy. I usually find my cotton fabric at Joann's or Hobby Lobby and use a coupon to get it for about $2-5/yard.

The hot sling-type, I also had extra fabric on hand so it didn't cost me anything. I would guess you would need about a half a yard, one yard, max. So, that would still be pretty inexpensive. Its pretty much just sewing a straight line - pretty easy, even for a novice like me.

I'll try to add pictures later, once baby is awake and can model for me. ;)
