r/letterwriters

Hello, I have two nieces recently in my life (brother adopted them) ages 13 and 17. Both are wonderful girls and have pretty good heads on their shoulders. We’re not super close, but we’re getting there and they both agreed they would love to try being penpals. I love writing letters, but for some reason, I just can’t seem to get going on this effort. How to open the letter itself? What to ask? How to draw them in? I’m hoping that the first letters they get from me are intriguing enough that they’ll want to actually respond. Thanks in advance for sharing any strategies that work for you in your letter writing!
