Fitted made from OV: How many body layers?

[BinahYeteirah]

I'm making a fitted from organic velour (short velour, if that matters) using the Very Baby AIO pattern. I've made a number of these in other fabrics, such as hemp fleece and hemp French terry, and I've found 2 body layers to be enough. I'm not going for super absorbency or anything; these are just newborn size right now. I'm just wondering if maybe the OV is too soft and stretchy to go without a third hidden layer (either of OV or another fabric). Most of the WAHM diapers I see made of OV have three body layers, but I just want to make sure I won't have too much bulk, especially in the wings, as this will be a turned a top-stitched diaper. I imagine the wings would be too thick with three layers of hemp fleece or hemp French terry; two layers seemed just right for those, but the OV isn't so heavy.

If you think I ought to use three layers, which fabric would be best for the middle layer? I have hemp fleece, hemp French terry, hemp jersey, Killington (or whatever it's called) unbleached diaper flannel, recycled t-shirt knit, and I don't know what else.

TIA!

If you are worried about stretch, I'd go with a layer of the unbleached diaper fabric - it won't really add bulk but will further stabilize everything to prevent the velour from stretching too much. As for the bulk involved with turning and topstitching, have you tried making your own bias tape or finding 100% cotton? I'm making pocket fitteds myself, but if I were to so regular fitteds that's the route I would probably take to avoid all the extra bulk at the seams (besides I hate top-stitching, but that's just me).
