Yes, I've made my signature below with PSP. I also make book covers with it.

Here are 2 links of the recent covers I've made. You can do a lot with this program. I feel like I've only touched the surface, and am lost to exactly all its capabilities!

Also, if you go to my site, and view the page marked "Art Gallery", I have a small slideshow of some of the pictures I've created with PSP. Though the sig says Miss Darolyn and Wanderer 1, they're still little ole me, Miss Mae.
