Help! Proper way to change colors

I am fairly new to knitting and need some help. I am making my daughter a hat knitting in the round I need to change colors, how do I do this? Any help will be appreciated. :oops:

What I often do is to knit a few stitches with the old and new color to secure the ends a bit so there is no hole then start knitting with the new color. Just leave a long enough tail on the old color to weave in a few more stitches.

You can also just start knitting with the new color. It sometimes leaves a little hole, but that can be fixed when weaving in.

Thanks so much, I knew it looked harder than it actually was. :happydance:
