If you're like me, you might do a lot of coloring on the iPad. If you ever download some PDF coloring sheets and want to color those on your iPad, here's how I've done it.
Download the PDF to your iPad
In Procreate, tap the Import button, then go to Recent and select the coloring sheet.
Add a new layer and rearrange the coloring sheet layer so it’s at the top
Set the coloring sheet layer to multiply and start coloring on the bottom layer!
