I have the dimension's figured on my personal blog, for how I'm going to do it. But It is very easy to figure. Each chart is 70 x 101. How many stitches do you want between each motif? What is your layout? calculate a total stitch width, by height and then go to:
www.crosstitch.com click on "TOOLS"; then click on "STITCH CALCULATOR" and put in the dimensions, the count and "over one" or "over , chose 2 inches or 3 inches for framing and press calculate and VIOLA! It will tell you the stitch area and what to cut for your framing needs depending on what you chose.
Just a FYI.... for those of you seeking help! I use this all the time :)
P.S. there's been a couple of you asking about my fabric, just go to my tutorial blog (http://tts-tutorials.blogspot.com) and click on Bake and Basted fabric - I have step by step pictorial instructions :)
