First off, think of it this way: You are designing the artwork and I am just bringing it to life. You let me know what you want, colors, themes, etc and I bring it all together. Second, these paintings are are custom made . This means they are unique and one of a kind. My personal way of thinking is I rather do my own artwork for the house instead of going out and buying it, but this way you aren't doing the work yet it is still personal.
The canvas I use is mainly canvas board. It comes in all sorts of sizes and it is much easier to ship. But if you are willing to pay extra, I can use a stretch canvas, a shaped canvas, etc. Also I have had some experience in making floor canvas' which can be used as decorative floor rugs or welcome mats.
