Definitely pick out your design first, then get the colors.In order to keep the cost down and the look professional I would put my first few designs on something that is not open to view on both sides as a towel is. I personally think it is very tacky to have both sides open to view and have the back side done in bobbin white or black. Colored bobbin thread adds more expense, so I would definitely suggest embroidering on pillowcases or sweatshirts or something similar to learn.I would also ask everyone to give me gift certificates as gifts when I could.
