What to say in the card

I'm so excited for you! We got our birthmom a sterling silver necklace of a heart with pinkish lavender jewels so she could always keep us & Nicole close to her heart & because her favorite color is purple. We had gotten to know her over the phone & loved her, but we did not get to meet her. She decided at the end it would be too hard emotionally so the adoption coordinator from the agency gave her the necklace. The adoption coordinator gave us the idea to give her a heart necklace, it was my idea to give her one with her favorite color stones.
