Obviously my product is quite different to yours, but I would imagine the benefits and pitfalls would be the same.
Different places have different policies regarding wholesale or SOR, wholesale is great as long as you have priced your work well-as it is an outright sale like any other, personally (having seen the state some of my work has been returned in ) with a product like yours ,that could get easily shop soiled or damaged I probably would avoid SOR.
I currently supply 5 shops , 2 wholesale + 3 SOR. "
The 2 wholesale ones found me via here , the others are more local and saw my work at craft fairs.
If approaching somewhere new I think it is always best to arrange an appointment - as often the person in the shop is not responsible for buying, or the timing could be inconvenient for them to give you any attention.
