Very simple to do and really cool looking when finished
Step 1: Find What You Want to Decorate With
My kitchen was decorated with all stuff chili peppers. Including chili pepper printed curtains that I had hand made to fit my kitchen windows and back door. Recently one of the curtains got ripped somehow and my fiancé changed the curtains. However you can still see the idea I'm trying to share in the picture.
Pick a poster or large picture that goes with your decor. Measure the slats in the mini blinds then cut into strips as wide as the poster and the same height as each slat. The idea is to tape the poster strips onto the slat of the mini blind. See the picture of before and after.
