Re: How do I go about finding a woven Mei Tai?
The FSOT forums at TBW (thebabywearer.com) tend to have lots of wrap conversions (I assume that's what you mean by a woven MT) and other more customized carriers. They do tend to be pricy, simply because converters charge at least $100 to convert a wrap and most wraps are at least $100 to begin with, so a wrap conversion ends up costing $200+ to make.
If you're trying to stay under $150 your best bet is a pre-made wrap conversion MT from a wrap manufacturer, such as a Hop-Tye or Didytai.
You can also check the facebook babywearing swap, there is a whole album there for wrap conversions, and I've seen some deals pop up. Good luck!
