"Noob" - that's cute!
Yes, you can just put three or four strands in a needle and start - that's a good way to start! But I'm lame, so I need to use an iron-on pattern - I'm just not coordinated enough to freehand or draw my own. Also, if the material is stretchy, you want to use an embroidery hoop, and put the stabilizer behind the fabric. Or you can draw the design ON the stabilizer and put the stabilizer on top, then wash it away when you are done. This keeps the fabric from getting all stretchy and wonky.
Hope that helps!
