Ordering What size elastics?

The minifee I had seemed to take the same size as my other 1/4 dolls, I assume the standard goes for feeple as well. So,

1/4: 3mm for arms loop, 3.5mm for body.
1/3: 3.5mm for arms, 4mm for body

With littlefee it's a little trickier because their stringing system is different (I believe there are 3 loops and an s-hook inside the body) so it's best to check in their respective discussion thread. A normal 1/6 doll would usually take 2.5mm/3mm elastic, though.
