Hello,
I just added all of the items and the pattern to my cart just fine so I am not sure what the issue is? All I did was push the "Check All" button at the bottom of the supply list and then hit the "Add to Cart" Button. It added the pattern and the floss for a total of 14 items. You can always call us at 1-800-800-8517 and we can take your order over the phone if you are having issues ordering online :) We are open Monday through Friday 8am to 5pm EST. Thank you :)
