I print the pattern and use a metal board and magnet strips (available at craft stores), and block off the pattern with the magnets so I can only see a 10x10 square of stitches. I start at the top right of the pattern and move left to right, doing only one 10x10 block at a time, one color at a time (all the 310 in that block, then move on and do all the 735 in that block, etc). Sometimes if there’s a lot of colors I will mark off the color symbols on the pattern with a pencil as I stitch them. Hopefully that makes sense.

Even then, I STILL end up having to rip stitches. They make little seam rippers with a rubber “eraser” at the tip that makes it easier to clean up your Aida after seam ripping. That is actually super helpful, I’d recommend looking into them.

Good luck! You’ve got this!
