What Kim said
we found with pockets we had compression leaks a lot - it needed a ... 'stopper' layer of hemp or bamboo to stem the compression leaks somewhat, if that makes sense, folding end to end
Drying time also as Kim said - you can combat this by having a longer booster that you fold in half, so a double long one of two layers that you fold in half to make four layers
you can have the twice or three times as wide, but single length ones, that you again fold but this time from edge to edge.
You can also do your boosters say, as is two layers, then stitch two of them together but only a line of stitching across one end... so that they 'flip' out (like a mobile lol) to dry when hanging.
Of course bamboo more absorbent than hemp, flip side is if it holds more it takes longer to dry so you have to weigh it up. Other choice is a hemp/bamboo combo insert if you're talking for pocket nappy. Hemp has been around longer here as a nappy fabric, than bamboo but people have issues with either depending on what it is - most people seem fairly happy with both but still have their preference.
There was a poll once about which fabric hemp/bamboo... will see if can find
eta
Hemp or bamboo
Bamboo, hemp or cotton???

there's two polls in there so should help you a bit in deciding - good luck!
