I make my own. I use a combo of flats, prefolds, and pockets ... Love my flats though, they're what Mom used with all of us. I guess I like all three types, although honestly anymore I use mostly prefolds or flats (dd2's nearly three, they're faster). I do love seeing flats drying on the clothesline ....
I use the kite fold; I have made both diaper flannel flats and birds-eye flats. Mom prefers the diaper flannel; her mother preferred birds-eye and so do I.
I don't use pins or snappis. I use the Bummis Original covers and they hold it in place just fine without anything else being used. This worked with my off-the-charts skinny dd1, and off-the-charts-chubby dd2.
To make:
I straighten the grain on the cloth first (snip along the selvedge, then hold both sides of the snip and rip across the fabric). Then, cut snips every 30 inches across the fabric (that's the width of one unfinished flat). Rip each one, then square it by ripping the other edge so that it's a 30 inch square.
To hem, fold over about 3/8 inch, then another 3/8 inch, and zig-zag around edges (I use up all my bits of bobbin thread on them). Don't worry about hemming the selvedge, it's finished enough.
I use the scraps from squaring the birds-eye, as backing for flannel/birdseye diaper wipes. 9 inch squares; sew together like a pocket (wrong sides together, leaving a 3 inch opening for flipping). Flip, zig-zag the edges closed/flat.
You want to pre-shrink birds-eye or diaper flannel before making the diapers, both will shrink!! You can find either in a fabric store (the clerks may not know what you're talking about, but it's often with their muslin, or else with the ticking fabric etc. -- a JoAnn's type store, not a quilt fabric store); or you can find it online too, although I've not ever ordered it online.
