DIY Paint Chip Easter Garland. So easy, thankfully no special punch needed. Tutorial from Modern Parents Messy Kids here.
DIY Paint Chip Wall. This is the best one I have seen. This has also been all over the internet and not correctly identified. Sally, who created this, used to be an interior designer and has thousands of paint chips (and can obviously put together colors!). Found at SallyTV – photo of finished wall here, and here it is in progress (shown for on purpose textured look) here.
