Why not start by just sewing same size blocks together. Buy a couple of charm packs from the quilt store. They are 5" squares ready to go and the colors in a pack all go together. You usually get about 40 squares to a pack. Start with simple and work from there. Sew about 8 of the squares together to make a long row, then make 8 or 9 of those rows. Sew one row onto the next and you'll have a nice size baby quilt. If you want to do borders, they are easy to add, just come back and ask. By that time I bet you can figure out what to do next. After your first project it gets easier. You sound as if you really want to learn and that is the first big step.
