It consisted of fitted diapers and covers.
The fitted diapers were made out of VERY good quality prefold diapers - and I used every bit of those prefold diapers! The part that was cut off on the sides was used to make the soaker in the middle (that is sewn in on the top only, so that it washes and dries more efficiently). They snap closed (but no snaps touch baby's tummy), and the tabs can be overlapped for a better fit (sometimes needed when going up to the next size). Elastic around legs and in the back, to keep potential "blow-outs" contained in the diaper. Sewed and surged on the edges for double fraying protection.
The covers consist of one layer of PUL (waterproof) fabric. The binding is done out of the same fabric, so moisture wicking isn't a problem. Some were done with velcro, and some were done with snaps.
Both have an extra layer of fabric behind the front closure part of the cover. So, no snaps rub on baby's tummy, and there is no possibility of leakage due to sewing the velcro onto the cover.
The velcro covers have tabs that can be overlapped for a better fit, and they also have wash tabs to secure the velcro during washes, so that it lasts longer and doesn't get "hooked" onto anything else in the wash :)
The snap covers have 2 full rows of snaps to keep them securely closed, and an extra layer of fabric to secure the snaps and ensure no ripping of the fabric (and therefore no leaking...). I have come to love snaps lately. They don't wear out like velcro does after a while...so you don't have to worry about replacing covers after multiple kiddos have used them (a problem we have run into even the 2nd time around on the size that is used for the longest amount of time.)
Now if I can just get the motivation to do some of this for our stash...
