This is an ideal time to flex your writing muscles, so show some class, and write a THANK YOU NOTE.
If you don't know what to write here's a simple template from a helpful site:
Thank you very much for the _________, it really was just what I wanted! Every time I use / wear the _________ I will think of you and your thoughtfulness. I wanted to take the time to write my thanks and I will call you soon, to thank you in person .
Best Wishes or Love
or With Grateful Thanks etc.
Write a note of thanks.
Happy New Year!!!
