I've found a shop on Etsy that is perfect for all your promoting needs. This shop is called Bitsy Creations, and there's a sister-shop called Bitsy's Greetings where you can find all kinds of great cards and stationary.
But my focus is on promotion items today. Now is the time that shops should be getting the materials they need to get the word out for Christmas shoppers. This postcard would be perfect to include with current orders. You could remind people about buying handmade Christmas presents, or you can promote a sale or just highlight a few items from your shop. Now's the time to start planning, and Bitsy Creations can help with Custom Postcard Design.
Or maybe you've just started your own business and you're looking for a professional logo to start the branding process. It's good to put your brand on your business cards, online or print advertisements, and product labels. Here's a great package to get you started with a custom logo and branding package made just for you.
And last but not least, I think it's very important to include thank you notes in with your orders. And it's even better if you can put your brand on those too. Bitsy Creations has these great customizable Thank You Cards. They're just the right size for including with your orders.
