well at least i wont have to buy flannel then. did you have problems with absorbency? did you make pfs or fitteds? i think i like the idea of folding pfs to catch the poosplosion better than fitteds. how many layers were they etc? i am still looking for more info before i actually make these.
My flannel diapers are all Rita's Rump pocket diapers and mostly stuff with diaper service quality Gerber prefolds. They are thin and definitely my favorite stuffer for the RRPs. I got them when my first was born 4 years ago and I haven't been able to find any "good" Gerber prefolds since then though.
I have one t-shirt prefold and I used Zorb as the soaker layer, I think 2 layers of Zorb (old kind) and 2 extra layers of t-shirt through the middle. Then two t-shirt layers for the whole body. That absorbed well. My t-shirt fitted diaper two body layers of t-shirt and then 6 extra layers in the soaker region. That one worked well too, but I used metal snaps on it because that's all they had at JoAnn's at the time and I ended up getting rid of the diaper.
I never got the hang of using prefolds as anything other than a trifold in a cover. I tried to do folds to get them to look like fitteds, but I never got them snug enough. I always get the RRPs snug enough though and they definitely contain the breastmilk poo well.
I believe I read that 8 layers of flannel or t-shirt is good for the soaker part, but I'm not sure if that include the body layer or not. Another suggestions would be to get old flannel receiving blankets and use those for soakers. I've found them for really cheap before. You also use the receiving blankets as a flat fold diaper. If you haven't tried flats, I suggest giving it a try. I used them occasionally with my daughter and they are really, really trim and snug. They wash and dry so easy. I do love them. I don't use them much on my toddler because she won't stay still long enough for me to get a good fit. Plus she is starting to use the potty and getting off a flat diaper quickly isn't the easiest.
