Hello,
You will need to contact the manufacturer of the kit. They will have any replacements you need for their product. Here is the link to the Bucilla website so you can contact them:

Just let them know what you need and they will take care of you. We are just the retailer who sells this kit, we aren't the manufacturers :)
