Knitting with multiple colors

hi im knitting a bag (for my knitting supplies). i already have a pattern but it calls for one solid color but i want to make the bag in 3 colors. wat i need to know is how do i add colors and carry them up the side without cutting or knotting? :?? :shrug: :think:

“Carrying Yarn Up the Side” is a posting I made on this Thread and the answer I got was wonderful!
You add the colors at the beginning of the row by starting the 1st stitch, but grabbing the new yarn instead of the previous yarn and then complete the stitch. There’s probably a video you can watch on that. It’s really simple. Then I usually make a [I]temporary[/I] knot until it’s time to carry it up or weave it in, whichever way you choose.
