You will need to add extra floss as your finished design on 14 count will be much larger. As it is not charted for this size, you will have to estimate which colours you will need more of.

EXACTLY WHAT IS YOUR QUESTIONS? If you are trying to order this pattern and the supplies -- click on the picture -- on the right you will see the order form. If you have specific questions regarding this project you need to contact Customer Service. They will be closed until Tuesday morning.

That project is so pretty and detailed! If you click on "view item" underneath the picture you will be directed to the ordering page. You will see "add to cart or add to wish list". Click on your preference and it will be added. Then click on the add all for your floss. You will most likely need more floss than suggested. I usually order double the suggested amount when I change to a 14 count. Also, for future reference, there is a fabric calculator under the item picture. I clicked on this when looking at your item. It suggested a piece of 14 count aida fabric of 26 by 22 inches. Now go back to the home page and you will click on "products". There is a drop down menu and click on "fabric" where you select the size and count of the fabric you need. Again, you will see "add to cart or add to wish list" option. Click on the one size that is closest to what you need.
