I had the finished project pictured in my mind.... a cozy, comfy, colorful garter stitch afghan. I wanted a border, 20 rows on the bottom and top, with a 20 stitch border on each side. My plan was to put squares and rectangles of different colors inside the border. I was happily knitting along, just started adding the colors. Everything was going fine on my first row of adding colors. But something happened on the way back. There is a big hole between where I left off with one color and joined the next. There is also a gap between the border and where I started using color. I tried to knit two stitches together to close the gap. I tried to pull up the stitch from the row below to close the gap. But that darn hole was still there. What the heck is going on and how do I keep this from happening?
