>>2889502An easel is a tool you use to hold the paper flat and create a sharp bordered frame. I use something like pic related. It's a nice convenience and really helps with ensuring the paper is in the same place every time.
These prints are nice for a beginner. If you like it, keep at it, it can be extremely rewarding, especially if you step up to medium format. If you don't know what that is, just start googling.
