Here are some local businesses that I think you will appreciate and enjoy.  

All of these are friends of mine.  You will find their services and products worth checking out.  As I am referring you to them, they will reflect on me.  I only refer people who are friendly, helpful, and who give a high quality product.  Many are Japanese speaking.

Wacha Sea crocheted bikini tops, string bottoms, Halters, scarves and more to wear to the beach or a party.  Wow! check these out...  (Regina speaks English and understands some Japanese.)
