Changing yarn from border color to main color

[1dove]

I am knitting an afgan that has a border all the way around. The border color on the sides of the afgan is 10 stitches, then the main color and then border color for 10 stitches. Will I need to cut the border color each row and how do I make it look even all the way around. Would I need to knit the border seperately and then somehow put it together with the central body of the afgan? I am really confused as to how this works and the pattern does not give any instructions as to how to do this. Please help. Thank you.

If the border is knit right on as you go you will need to do intarsia for the border. That would mean you work the 10 border stitches with the border color then leave that color there and start working with the main color. Work across to the second border and drop the MC there and start a new ball of the contrast color. Then when you work back you drop the border color and pick up the MC, work across and drop the MC and pick up the CC for the border and keep working like that. The thing you need to remember is that you will always pick up the new color, at each change, from underneath the color you are dropping, this caused the yarns to twist around each other. If you don't do that you will have an open space between the two colors, they will only be side by side, but not connected. There is a video about intarsia on this site. I believe it is list
