What our clients are saying!

"I enjoyed how easy and seamless the process was and that it didn't take a lot of effort from me to get the end result that I had been dreaming of. It was definitely the right situation for me as I wanted to have some say in the design process, but also wanted to be able to tell someone my ideas and let them be able to bring them to life. I thoroughly enjoyed the process and I am so happy with how they turned out. It really was so nice of you to help us out when our wedding was postponed during all this craziness! Working with you was a really easy enjoyable experience and it is something that I do not take for granted during this busy season of wedding life."

"My wedding invitations turned out so beautiful that I may have shed a tear when I opened the package. Working with Jill was easy and I’m very pleased at the final result. I won’t hesitate to order invitations from The Letter Box in the future."
- Lauren
"Working with Jill was a dream. As the mother of the bride, I hired Jill to do the envelope calligraphy for my daughter’s wedding. She did 155 inner envelopes and 155 outer envelopes with zero errors! She communicated with me every step of the way. We worked long distance by mailing the envelopes to each other. Even though I haven’t met Jill, it felt like working with a friend."

"Jill did absolutely beautiful envelope calligraphy for my daughter’s wedding invitations. I just sent out the invitations and I am so proud of the way they look."
