Small hole in intarsia

I just completed my first intarsia project with the help of the videos here on Knitting Help and overall it turned out great but at the first color change there is a small hole where the two stitches are not linked. I twisted color changes on each row, but as this is where the yarn end starts, there wasn’t really anything to twist with. I was able to close the holes well enough for the project (it is a stocking) but not well enough if it were a piece of clothing. Does anyone have an idea on how to prevent this small hole or what to do to close them up when I weave in my ends?

When you have two loose ends you can cross them and weave in on the opposite side which will help close that hole.
