Q: floor underlayment as shelf liner
I have seen it mentioned several times as a cost-effective alternative to other shelf liners.
I know there is cork underlayment but I there are other kinds too, right?
As an underlayment is meant for floors, is it food-safe? Even though I am not putting food on it, I am still a little concerned about cooking utensils being in contact with.
Which one have you used and why?
