she is at school right now and is not doing a lot of requests but read below to see how you can add a text box in word to add your own names
Also, Natalie has a lot of great envelopes that you can add their names to in her shared file. Like in the folder called mailing envelopes:

Here is how you can add a text box over the are you would like to put your grandchild's name in or if you find a blank you can print and write the name in.
Text Box
Make sure that your cursor is below the image that you want to insert a text box over.
Then look for the tab at the top of word that says "insert".
Scroll down and click on "text box".
A big box will show up on the screen that says text box...ignore this box but look for your mouse that will show up as an +. Move the +/mouse to where you want your text box to go then left click and drag the mouse to make the size box you want for the area you want the wording to go.
Then go back up to the top of word and click on "format".
Then click on "text box".
Look for the tab that says "colors and lines".
In the line section make sure the color says "no line"
In the fill section make sure the color box says "no color" for Natalie's DISigns but if you are trying to cover over another name that you don't want to see in MCraft17's DISigns...change the color to whatever color you would like the box to be or leave it white
Then the background will show through behind whatever text you type in the box and there won't be a line around the text box.
Then you can type whatever you want inside the box by clicking inside the box and choosing font and size.
If the box isn't the right size you can drag the corners and sides to make it the right size.
Hope this helps!
