A good entry level quilt would be that uses just straight stitches on square blocks of plain patterned color fabrics (solids) Plotting out your idea on a piece of graph paper is a big plus. I would start with a small quilt that they call a sampler. As long as you can make a straight stitch, you can make this type of quilt. Then once you get accustomed to that form of quilting , then you can start using triangles and curves, Slow and easy wins the race with the sewing machine. I always use th slowest speed when sewing so that the machine does not get ahead of my thinking. There are many videos and free instructions on the internet and investing in a book on the basics of quilting helps. Fons and Porter has a book on basics. That is how i learned to quilt.
