It sounds like more of a decorative item than a utilitarian one. I can only say that if people want them enough to pay $8 or $10 ea., I'd think about selling some.
For me to sell hand knitted items and feel I'd made anything my price would probably be so high nobody would pay it.
As far as a reasonable price to ask, I hope somebody can give you a better answer.
