You can check out my other tutorials are the following links Colouring with the Fill Bucket in SAI: [link] Shading with Masks in SAI: [link] Lineart in Inkscape: [link]
Sorry if this is a silly question but are these tutorials meant for people with tablets and SAI or just everyone with SAI? I only have a mouse unfortunately. xD
Oh sorry. More or less - as that's what I use nowadays. But if you have really good control with a mouse, you should be able to manage. That's how I used to do things before I got my tablet
