I sew enough to do a gathered shoulder ring sling.
Doing a mei tai or SSC just seems beyond me.
Actuallly, I was just coming back here to point out that it's not about "brands" - people also need to be aware that for less than the cost of a Moby (already the cheapest of the wraps), one can make a Fauxby, even if you can't sew! And gathered shoulder ring slings are within the reach of anyone who can do a straight line. Same with podaegis. Mei tais (although beyond my comfort zone
) and pouches are still pretty easy. Even SSCs are doable.
But even people on a budget don't necessarily want to have to make something. For all the reasons listed in this thread (and more), most people will still use the big name carriers, whatever those are at the time. The important thing in my opinion is to support babywearing no matter how and with what, and to let people know there are options
(smaller names, different types, easy DIY instructions) so that they can choose what works best for them. But that's still often going to be a big name, easily available, relatively cheap carrier, and that's ok.
