New knitters have heard about dropped stitches so they're terrified that one will, so they tend to knit too tight and keep them away from the tips. The truth is, they don't drop and run that easily, so if one falls off you would just put it back on. It won't run down unless you pull on the knitting or the stitch. The videos on the Tips page show how to fix mistakes, including a dropped one that you don't see and put back on but keep knitting. You could practice doing that on your samples then you'll have more confidence by knowing you're able to fix problems.
