Thank you for the sign you made for Salem Baptist Church. I have to thank you particularly for not doing what I originally asked for!
I really appreciated the fact that you considered my request and offered me the benefit of your experience. You were very patient in discussing it with me through a series of emails. The final result was a copy of a sign you had made for us some years ago, and it has been much admired by all who have seen it. It is perfect for our purpose, and a vast improvement on my idea.
Thank you again, and I shall be delighted to recommend you to anyone who needs signs made.
