I so dislike having to weave the ends in whenever I'm changing colors or starting a new skein of yarn on a project. It seems like no matter how careful I am, the ends still seem to work their way out, especially after washing my item (*snip* *snip* *sigh*).
I ran across this great idea on Pinterest.com and wanted to share it with y'all. I love Pinterest! There are the most awesome free patterns and wonderful crochet project ideas on the site.
Here is a great video about how to change colors in crochet without knots. It is an easy method, and you will not have any ends left to weave in. I've used it many times. It is sturdy and doesn't come undone at all.
Every since I saw the video how to do the russian join it is the only way i use to change yarn whether I'm adding a skien or changing colors. So far I have not had it come undone. LOVE LOVE LOVE this way of joinging yarn! It makes your work look flawless too.
