If you use cloth wipes...
Do you prefer single or double layer?
Dosen't matter. Most of them are terry on one side and flannel on the other. Sometimes I use baby washcloths.
Do you prefer serged or turned and top stitched?
uuuuhhhhh...I know nothing of these sewing terms lol.
Do you prefer to keep them wet or wet them as you use them?
Wet as I use them. I forgot about some pre-wet ones once and they became covered in mildew! ick
What do you use to get them wet (spray bottle, peri bottle, etc)?
Spray bottle when using the changing table, sink everywhere else
Do you use water or some kind of soap?
Just water when using a sink, the spray bottle is a mix of water lavender and tea tree oil. It smells great
If you use soap, what do you use?
Soap on my babe's bum? Never even considered it, isn't that bad for their skin?
