I have just learned how to knit and have knitted 8x8 squares. I do not know how to put them together. Could you help me?

Put the right sides of two squares together and stitch them with wool, use an over stitch, put your needle onto the first two squares, push it through both squares then pull it out, pass needle over the top of the squares and do the same thing again. Keep wool tight so stitches don't show on the right side
