If you have an iPhone 6 there is an app that comes with it called “Memo”. It allows you to draw on the screen with your finger. Go to “Notes”. Click on the plus sign. Then click on the squiggle. A selection of drawing tools comes up. There is a black circle to the right of the tools. Click on it to get to the color options.The trouble with finger art is a lack of control. For example you have to look part way down the page to find my colored-in boat drawing.
I love the challenge! Failures are simply new discoveries!
Please share your attempts! And enjoy the option of being able to draw anywhere, any time- since who is ever without phone any more?!
