A mood board is a great way of articulating your vision.
It’s a fun and creative process that involves finding images from magazines or the internet, paint swatches, pieces of fabric you love, lifestyle inspiration, personal pictures and place them all together that represents your vision. This keeps you focused and gives you free reign to get expressive and experimental. You don’t have to stick with every idea that’s on your board but it keeps you on track. There are apps too like Pinterest.com that allows you to do the same thing only online, which is great and can be shared with others if wanted.
Try to pick images that include the following: Texture - Design elements/inspiration - Lifestyle images - Colour palette swatches
