I first got a ring sling with #4 and LOVED it (before i'd had snuggli type things and refused to use them they are horrible!) it was easyto just pop on and slide baby into, nurse, walk, garden, hike part of the apalachian trail with a 3wk old... yeah its great for all of it

I even carried #4 on my back at 18mo, a week overdue with #5 playing mini golf (by the way AWSOME counterweight for preggy belly!!!! toddler on back in a sling, it was the best i felt the last 2 months!) I love the range it can work for but teh one bad thing is, the weight end up on one shoulder and can get rough at times.
I ended up getting some stretchy, knit/wove sort of look fabric for like $50 a yard so figured i'd try making a wrap, didnt want to spend the cash becasue like you said, i didnt think i'd like the fabric wrapping me up. I wore it swimming, to the fairs, all over in life, at teh store everywhere, a little tug here and scoot there and i could easily nurse AND walk with other children in tow, pushing a stroller/cart or whatever. on real hot days i'd just put teh wrap on with no shirt and once wrapped up just give a couple tugs to make sure i was desent. if i was out somewhere i woud just slide baby in and out and keep the wrap on. I found if i wrapped it just right it was like a built in back support too. I'm absolutely in love with the wrap now and sort of went crazy when i found out i was preg again... i now have 6. The great thing is, the fabric i got, i split in half length way so i got 2 wraps out of each piece, kept one and gave the other as a gift!

I even got my metal head, airborne ranger, to tough for anything DH to wear the first wrap, he said the other day if i found camo fabric for him he would wear one to carry the 21mo

i'd strongly suggest getting some inexpensive fabric and trying a wrap, pick fabric you would use for something else just incase you dont like it... you can make one for under $10. dont even have to stitch it if you get something that doesn fray.
As someone mentioned, you could see if a maternity store or the like has some to try out. We dont have any that i know of

Possibly even a good heath food/healthy living sort of store might carry a few??? They might know where to look if they dont.
