This object is a cup sleeve. It's purpose is to provide a grip-able surface for when you have a hot beverage in the cup. I noticed this object has lots of gaps in the sleeve. It is circular, so I would have to design it like that. If I customized this I would make it thicker so that you could have a larger surface to hold the cup. I would also change it to not have any gaps so you could also hold it easier. However, I do like the customizable word/number element to it, so maybe I could have a gap-less surface and on top I would have words or numbers.
This object is a napkin holder. It has two rectangles of different sizes stacked upon each other for the base. On top of that, is two half circles parallel to each other. In between the half circles is where you put the napkins. If I were to design this, I would definitely keep the base because it is very sturdy.
