It looks like this is a pattern only. Which means that you would/could purchase the fabric and the thread separately. Therefore it would be easy to purchase extra fabric and add the names at the top and the date at the bottom or however you wanted to do it. The first thing to do is to post a note on here asking Kristi to list the supplies so you know how much fabric you would need. Then add 3 or 4 inches each for the top and bottom. For instance, if the supplies call for a piece of fabric 10 inches wide by 17 inches long, add another 4 inches to the 17 to allow for space to stitch the names and date. There are also a lot of books that will provide sample alphabets. And you may want to add a lot more fabric to the length which will give you the flexibility to stitch the name/date in any style you want. Trust me, it's a lot easier to cut off any excess fabric than it is to add more of you calculate wrong!

Good luck and enjoy the process.

This is definitely going to be unique. The supplies are already listed. Find an alphabet you like. Use graph paper to spell out names, date, etc. Pay attention to the font size you want to stitch. Count carefully and add the amount to the suggested fabric size. Adorable. Please post pictures.

FYI: crosstitch.com has "caption maker" tool that could be VERY helpful. You type in the words and have the ability to see it in several different fonts. Try it. You'll like it!

Kathy, Kristi at ECS has already posted the needed supplies for this pattern. I looked at the customer comment section to see a previous customer purchased this pattern and added names and dates to it. It would probably be good to double check the amount of fabric needed.
You should be fine. Diana
