You can cover it- paint or stucco- https://www.sapling.com/5821481/cheap-disguise-cinder-block-wall

Paint the wall a favorite color then do some fun artwork

if it is in a kids room, let them do the art work

use painters tape to make a design then paint the spaces different colors

Paint, or do a faux paint like sponge painting; which is fairly quick and easy. Another faux paint job I like is called Smooshing. Basically you paint the wall with light color, let this coat dry well, Paint a new coat in darker color but this coat needs to dry slow, so use oil based, or add a drying extender to latex paint. Then using large plastic sheet (like 0.5mil), apply plastic to wet paint, them rub it all around; then peel off the plastic and discard. Will give wall a fabric sort of look. You can reverse colors, dark first coat, then light second; just depend on what you want. Google Faux Finish Smooshing and click IMAGES.

A bit of italy......

Buy a bucket of drywall mud and use a trowel to smear it on the blocks. Make sure to not go to thick. Don't do it even. You want it to look like an old wall in Italy. Let dry completely . Now paint your first color on , Yellow is really pretty for this. Paint it and let dry. Now get a can of semi transparent stain. A brown that looks like wood is really pretty. Do this in sections of 3x3. Paint it on then take an old t-shirt or something of the sort and wipe it off so that the stain stays in the cracks of the mud. Don't over wipe it off. Wala !!! You have a wall that looks like your in Italy. You can even buy a poster of a window and place it in the wet mud , but smooth that part out behind the poster. Then mud around the edges of it as you go. It ends up beautiful. My whole house is done this way. People love to come over. They say they feel like there on vacation or something. Good luck.........
