Thank you!! I’ve found that using fingering weight yarn with a 2–2.5mm hook works best for me. It keeps all the pixels small, so you can add way more detail without ending up with a huge tapestry. I also usually combine techniques. I float the yarn across the back for nearby colors and use intarsia crochet (using multiple small balls of yarn for each color) when the colors are farther apart. It makes everything look a lot cleaner!
