Praline & Cream Fudge: Pralines and Cream fudge is one of my top 3 favorite flavors (I can’t pick a favorite, the 3 faves just keep up a continual rotation), and it is SO easy to replicate at home. requires no candy thermometer or crazy technique.
DIY: lace patterned light bulbs - just spray paint a lace doily or piece of fabric onto a lightbulb or even use a silver or black sharpie pen to draw your own design and the then the light will shine through to cast a pretty pattern on your walls.
Seashell paint makeover: spray paint inside of shells high gloss baby blue and paint outside with gold or silver paint. Maybe could do this with something else from nature if your home isn't beach themed.
