I participate in one affiliate program. That means I receive a commission when products are purchased through links here at this blog. There is no additional cost to you. The affiliate program to which I belong is for Papertrey Ink.
I also receive product each month from Papertrey Ink to use for blog posts. This is considered payment, but I am always completely honest about my opinions regarding these products.
I also earn royalties on any products I personally design for Papertrey Ink. That being said, I believe in Papertrey Ink's products and would not work for them or support them unless I did.
I do not do sponsored posts (those in which I am paid to talk about a product).
In the (incredibly unlikely) event that someone sends me a product to review I will be sure to mention that in the post itself.
I purchase many of my own supplies and only discuss products I truly enjoy using.
