Guys how can i make pony manes like regenboog dash? using ms paint?

Use a pencil of a paint brush, of use a base

draw a mane of uze baze

1. Copy Paste a base
2. Make the color in your palette something different from the base (for ex. if the base is black and white, make your color red)
3. Use curve tool to trace out the lines in the base
4. Make your initial color white and use "fill" to the base lines to erase them
5. Color the lines u made into whatever color u want and proceed to making your pony.

Other ways...
1. Copy-paste a pic of RD
2. Make your canvas bigger/longer
3. Make your pony while using the foto u Copy-pasted as reference.
4. Profi- jk jk :P
