What fabric for face wipes?

I need to buy some more wipes for bums at some point but I'm also looking to get some little wipes for cleaning Iona's face. Being a preemie she has really delicate skin and with being sick a lot she needs her face wiping a lot so something supersoft is very important.

I've been using cheeky wipes to wipe her face but they seem really rough (and with the size of her one wipe reaches from the top of her head to below her nipples ) but I'm not sure what fabric to look for wipes in as most places I've looked just seem to have cotton ones like the CW.

I was pondering about OBV as I can't think of anything more lovely and soft (plus it's pretty lol) but I wasn't sure if it would be any good for wipes or not?

I use obv, dyed bamboo fleece and minky for wipes for the kids so any of those would be lovely and soft for faces

i just used a muslin for DD, who vomited sooo much in the early days/weeks. now i use the same wipes for bum and face (but wash them of course lol!). OBV is super soft and so is fleece. xxx

We're loving our Looby Lu's wipes at the moment... we save them for DDs face (they're pretty), and just use boring plain ones on her bottom
