I just wanted to make my blanket statement about Playscapes/AI2s, lol. I will do them with an OBV outer if requested, but some people find that they wick more than with a different outer fabric. Some people swear by them too, so it is a personal preference thing it seems. I usually do the PlayScapes with a woven or knit cotton outer. Just wanted to make sure I out that out there so you can adjust you orders if desired
It's also been discussed recently on here, I'll try and find a link for you.
Personally we don't get on with them at all - the cotton outer wicks terribly, they're not great for heavy wetters at all.
