yeah Libbie, i did the chart myself. I had never done embroidery, so I just did the only way my mind could think of and later found out that what I did was called duplicate stitching.
Acrylic and fleece does work in a similar way to wool, except for one big difference - with wool, if not soiled with poop, all you have to do is air it awhile then when you do the sniff test there’ll be no urine smell - if it does smell, it means you need to wash (and maybe lanolise it). So you only wash the soakers/longies once a week (I have a few of them, so I probably only wash the wool covers once in 3 weeks?). Fleece and acrylic do not have that anti-microbial property so they’d stink of wee easily, ie you’d have to wash them after each use possibly.
Bummis Whisper Pants is similar to Dappi I think, very thin PUL nylon so great for trimness to reduce bulk of cloth diapers. You’ll get more wicking (ie moisture coming through the cover) with wool than something like the WP or Dappi so make sure you have more absorbency in the diaper itself.
