There are tons of printers to choose from to print your templates and marketing materials. Whomever you choose, be absolutely sure that you contact them for their sizing, bleed and crop specs before printing your materials. You may need to re-size to their specs or move text away from the edges. Never guesstimate and always double check with your printer before placing your order! That said, we do have a company that we recommend:
Miller's Lab for tri-fold cards, stickers, flat cards and wallet-sized accordion books, 8-page and 16-page booklets, postcards, business cards, stationery, holiday card ornaments, specialty press products.
