If you wish to do more in MSPaint, you should look at this as an example of what can be done. You should also be made aware that there are other programs that can do the job as well, and with plenty more options, and usually faster too. Paint.Net (PdN) is one such prog that was designed as a Paint substitute. If you want some tuts with PdN, look up posts by PeaceHeather in the tutorials section.

Which ever prog you end up using, I wish you many "lost" hours of exploring the worlds of you mind See you in the WIPS.
