I have a Kitchenaid mixture and use it all the time. I do have a splatter shield but when I am making a large recipe of something like butter cream there is bound to be a mess. Powdered sugar is always an obstacle to not get a cloud of it in the air even when you are careful. This is a simple solution that I saw and have used regularly. Such a cheap solution that can just be thrown away when I am done. Just take a piece of plastic cling and wrap it around the opening to the mixer. It keeps everything in the bowl and confined to that area. This also allows me to do other prep work while the mixer is beating something that has to take awhile.
Here is a great idea for a small space. it is creative and actually rather cool. Using cut timber from a tree in fall branches are attached to a wall. Now, you could just attach to a 2×4 like a trunk of a tree and screwed at the top with a simple bracket into the wall. A strand of white lights was plugged in and run from branch to branch. Ornaments are hung from the wood with little picture hanging nails. The light cord is allowed to show and not kept tidy or hidden as part of the design. But, you could be as neat as you like. Little items can be set on top of the timber. Can be made from floor to ceiling and can be made to make a big impact. The wood could even be painted a Christmas tree green or hot pink – thats up to you.
