I love this photos, painted wooden boards, mod podge, ribbon. Simple home decor. Love the idea of doing black and white prints of the kids. Tip: with mod podge you can print on plain paper from your printer to save money.
Paint samples are really cheap (cheaper at Lowes than Walmart). Grab a blank canvas (also cheap), use painters tape to make a design, and buy a size appropriate wooden letter, or smaller letters to make a word, and paint those= Awesome art.
