I looked in EQ7 (I'm no expert either), but I could not for the life of me find a Grandmother FG layout. So...you can start your own new quilt. To make your blocks, you will need to click "work on block", then use the Patchdraw option. Click on the tiny arrow on the symbol on the left hand column that shows the triangle. A little menu will pop out and you can click on the hexagon from there. Place it on your block...make it whatever size you want, then click the heavy black arrow (the select tool), left click to select your hex, then right click to copy it. You can then paste a lot of them into whatever size block you will be placing on your quilt layout.
Also if you click on the topic lists on the bottom of this page...I'm pretty sure there is an EQ section...lots of help there too.
Good luck and have fun!
