4. Stay Inside Lines: Your kindergarten teacher was right about this one - it definitely makes for the best results. With the more detailed paint by number designs it can actually be quite hard. I bought a special fine artists brush to help me do this. It only cost a few dollars and it lasts a very long time. 5. Get Creative with the Colors: You don't have to stick exactly to the colors listed on the numbering sheet. Often your picture just looks better if you add a bit of white or yellow to the color listed. This is true especially if you want your painting to look very similar to the original. I enjoy experimenting with the colors, and I do it more as I get more experienced with paint-by-number N. The most important thing is definitely to relax and let your creative juices flow. Enjoy this time that you've taken for yourself!
