Since this is the first ever tutorial/tip issue, I'll write some very basic stuff for those who aren't so familiar with this traditional medium~
Issue 1: The Watercolour Artist's Tools and Tips! Part 1
Sketching/Lineart Mediums
Pencil:
It is mostly used for sketch for pre-watercolour planning. You can go nuts with the lines when you're planning out the picture but please do not do that when you're drawing out the final lineart on the watercolour paper. Why? It's because pencils can smudge and leave ugly black/grey hue which would ruin the colours of your watercolour paints. If you're doing lineart, make sure the pencil marks are minimal by making sure you actually PLAN OUT the piece first and then head onto the final task. Why not erase all the mistake?? Well, the rubber (or erasers for Americans) doesn't rub off ALL the pencil marks perfectly and watercolour papers are not the best papers to rub off mistake with because of it's absorbency.
Alternative tool >> Mechanical Pencil.
Mechanical Pencil:
Mechanical pencils are great because you can keep the same thickness of the line and you don't need to sharpen it so often when it gets blunt again. Not only that, it keeps the lines thin which is what you want for your watercolour works (unless you're inking but you don't need your pencil lineart to be thick!) What I do is, I firstly draw the sketch on the A4 printer paper (It's great because it's thin and quite transparent) and then trace the line on the watercolour paper using the light table. I trace it out with the mechanical pencil because it's thin and easy to use compared to the traditional wooden pencil.
Ink Pen:
There are lots of different types out there. There's fountain pen, nib pen etc. Find what's right for you when inking... but beware, this tool can be quite costly.
Alternative tools >> Gel pen, Waterproof drawing ink, Felt tip pen, "Sharpies".
Felt tip pen:
You can purchase these easily at any stationery shops. They are easy to use and they work really well on papers!
WARNING: Never ever ink with this tool before watercolouring!! It will cause the ink to bleed and this will cause a big catastrophic disaster if you do!
Gel Pen:
Same as the Felt tip pen except they are more cheaper and more easily rolled on paper. It has a nicer feel to it if you try inking with this.
WARNING: Same thing as the Felt tip pen!! Never ever ink before watercolouring!!
Sharpies:
If you don't know what "Sharpies" are, I'll show you the link: [link]
Sharpies are great because of the boldness!! They are permanent markers but comes in different thickness (and thinness)~ They costs more than Gel and Felt tip pen but they come in lots of different sizes and colour!
WARNING: Same thing as the Felt tip pen!! Never ever ink before watercolouring!!
Waterproof Drawing Ink:
I only used (and known) one brand of this medium: Atelier Waterproof Drawing Ink This is a great medium when you want to ink before you watercolour! But, you ink this medium using a brush only because it's so thick, the nib pen won't be able to apply it.
Thanks for reading this! Hope it helps you with the idea about the medium and I hope it is useful too!
