I seem to find that sitting down for a short period painting on canvas really helps with alot of issues that I have been having with my health. That being said there are a number of companies out there that provide art supplies. My favorite company is USArtSupply. I recently was given the opportunity to try one of their products which was a canvas variety pack. Their products are made of quality materials and are very thoughtfully made. You can find them on Amazon.com and I will provide you with the link for their listings below. I just wanted to share their product with you because if you are an artist these are affordable, easy to use, and are made of top quality!! I will give you a little information straight from their listing and if you give them a try make sure to tell them that Tizzy sent you.

These are also perfect for children and if you look at my posting below this you will see the art easel that makes painting on these a breeze. They are both by the same company and they are really great products. I am so happy that I was given the chance to review them. Happy Painting!!!
