A couple suggestions I always gave my kids for writing thank-yous: Each note should have at least three sentences.

(1)State the gift you recieved.."thank you for the pretty stationery" If it is a cash gift, simply call it cash, check, etc. No need to state the amount.

(2) Make a personal comment. "I really needed some stationery and especially like the color blue". If the gift is cash - tell the person what you hope to use it for. "I have been planning to use it to buy a new CD I have been wanting" or "I am putting the money towards an MP3 player I am saving for"

(3) Say thank you again

I feel that including these things in a note indicates that you are thanking someone for a specific gift and not just writing multiple versions of the same note. It lets the person know that you appreciate the gift and have plans for using it. Saying thank you again is a good way to end the note.

Good for you asking for suggestions about writing your notes. Try to get to them quickly and perhaps only write 3-4 at a sitting so you don't get too tired of writing things and to keep your comments fresh. Receiving a thank you note can be a very happy and affirming gesture for the person who cared enough to get something for you.
