An alternative is to bring the needle to the fabric and gently smooth the remaining floss with your fingers. If tangles are a problem - it is often because the leading end is frayed. Snip it off occasionally, or when you experience knotting. Enlarge or reduce patterns to fit various projects you may envision for your finished work. Don't be frustrated by your first few attempts.
Embroidery takes persistence, but the rewards are great.
Learning takes time. Some stitches will go quickly. Others take patience. Experiment with color. One of the easiest ways to learn about color is to take a garment with a medium-sized print and embroider the design using matching floss colors.
