Hey, S.!
At the risk of this being a shameless plug, I have a baby sling company called THING-A-MA-SLING, and in addition to making full-size infant/child carriers, I also make "Mini-Thingy" doll slings! They're pretty inexpensive & I have a nice variety of fabric to choose from (plus several fabrics that aren't currently listed online).
They're a really fun way for children to role play.
I recently launched my new site (which is a HUGE step up from my old site!) and am offering 10% off till Friday by entering coupon code "UPGRADE" during the checkout. The site is www.ThingaMaSling.com
If you live anywhere near Easton, I'd be happy to meet you to save you the shipping charges.
For standard "toys" I really love www.RosieHippo.com and www.MagicCabin.com for natural toys (some of which are American-made).
Good luck!
A.
