Ok, I just started doing the border but with a lot of uncertainy. So much the I've been paralyzed with indecision and the project is on hold...
When picking up the stitches the first time, I cannot tell if I've picked up too few or too many. I think you have to knit a couple of rows before you can tell if the number of stitches affects the rest of the garments.
I think I am picking up 4 stitches every 6 rows. If I alter that ratio it looks like the stitches are picked up unevenly - some stitches are closer, some are further apart.
Then the next problem is exacty where I am picking up. A detail I left out is that every switch from garter to stockinette, I am changing colors by carrying up yarn (think an illusion, or shadow knit project).
So I picked up in between the yarn used for carrying up during a color change, but this looked like it was leaving a gap effect, due to these areas being looser than normal stitches.
Then I tried to pick up inside the first stitch, but because I have this extra carry up yarn, this leaves a very noticeable inside edge after the border will be done. I have a feeling this could be uncomfortable when wearing the scarf.
I'm not sure exactly how to proceed, or should I abandon my border efforts...
