Hi and Welcome
I think a blanket would be a big project too. When you get some basic stitches down, I would recommend something along the lines of a dishcloth, scarf, and/or shawl.
They are all easy fun, & useful as well.

as well. They have a bunch of free patterns. I often look over the patterns there and get ideas for all kinds of projects.
