I would like to send a notice to my frequent customers and need help with the wording. I work from home in a CFL state. I am going to go back to my "real" profession (nursing) and am not going to take any orders after June. I will probably reopen the business on a limited and restructured basis some time in the fall or early winter.

Do I give the reason why? Do I need to give parameters for how things will be after I reopen because I am not sure?

I might include a little bit of the reason, if it can be stated succinctly and without too much personal info..."Due to a family emergency" or something similar.

I wouldn't say anything about your anticipated restructuring, just say that you hope to be able to resume taking orders sometime this fall, or whenever it was. You can explain any changes to them if/when they order from you again.

I'd write something like this:

Dear clients,

I am writing to let you know about some changes that I'm going to be making to my business starting in June.

I was recently offered an exciting new job that I couldn't turn down, so as of June I will be putting my cake business on hold for a while. Once my "baking sabbatical" is over, most likely later in the year, I'll be getting in touch to let you know how I plan on handling orders.

Thanks for your business in the past, and I look forward to making more cakes for you in the future. Please let me know if you have any questions!

The suggestions above are good ones. I like CostumeCzar's wording, and you can tweak it as needed.

Vista Print can prepare something that looks professional in a postcard format for very little money.

Thank you all for your help and suggestions, costumeczar...you have a wonderful way with words!!
