I've been using them over the past few of years for all kinds of projects from business brainstorms, home renovation projects research, dreams and goals, a daily to do list and now I am using them for client projects I am taking on. They are the perfect size and so sturdy, easy to tuck inside a purse, backpack or carry on. I use a file rubber band to hold things inside, so it's easy to tuck things in as well. Sometimes I glue things inside.
I grabbed a stack of eight on Monday and am already using two but am really happy to have a stash in my cupboard for the future. I have one I've had for a while that I am using to track projects for the house and I have added tabs on the edge with the name of each room in the house so that I can easily find and flip to each space.
They are great for sketching ideas out and I love being able to keep all my thoughts and brainstorming out projects in one place. They would be great for a travel journal for a trip. With some fun washi tape or a glue stick with you, you could tape or glue tickets and photos and fun mementos inside along with a daily record of activities and events - and again they are easy to tuck in a small bag or write in while traveling in small quarters.
They would also work great for a place to collect recipes, collect favorite quotes or to use a a gratitude journal each day -- and they look cute on the bookshelves too. One dollar composition notebooks are my Big Like for this week.
