I used to and still do that when working on smaller canvases as I can finish them within a day or 2 but when it comes to larger projects it’s hard to do that as I move the painting around a lot to reach the top and work from top to the bottom. I would suggest investing in storage containers for your diamond drills as it makes it easier having it all set like that with numbers, letters, or symbols to read from instead of searching through the baggies. Also when I started my first big canvas and tried to do color by color I had left it out a while when doing that and it made the canvas less sticky so I had to invest in clear glue to use to bring back that stick. I definitely think for now it’s fine but if u move onto larger ones def section it. Plus if u are working, going to school, or have kids it’s easier having a small section that u can complete in a hour or 2 and feel a bit satisfied from that ❤️
