Using this patch is a breeze. First, if you want, you can use the ironing adhesive on the back to stick it to your shield, coat of arms, or banner. This gives you a chance to position it perfectly. After that, sew it on for a more permanent hold. Before sewing, if you notice that some parts of the cross aren't cut out, just grab a scalpel and finish the job. As for maintenance, since it's made of cotton canvas and polyester, you can gently spot - clean it with a mild detergent if it gets dirty. Avoid machine - washing as it might damage the patch. Keep it away from sharp objects to prevent any tears. That's all you need to know to enjoy your Knights Templar cross patch for a long time!
