Repurpose Services or another Section?

Hi, in an old thread I repurposed Testimonials to use for some things we wanted to feature. The site turned out really well. Now we'd like to do the same thing to feature a new collection of jewelry. The site is JohnDMaddinArt.com I'm not sure if three or four columns will be the ideal but can work with either. As before, the name of the section and the font would change. I know the Testimonials section received actual updates to help with this and don't know if the same applies to Services, or if another section would be a better choice. The plan is to add another row of boxes between Featured and Recent Posts. It would also be good to know if I need to plan on another band of background image to fit in between, and where I would do that. Thank you!
