All About Me Scratch

When I started with Scratch, I found it quite easy but some of the things were hard to understand. When I wanted to show an item only on one screen, I tried and at the start I didn't understand how to do it, when I asked for help from someone else in the class, he showed me how to use "hide" and "show" and it worked!

Next, I want to start doing games on Scratch, I'll start with simple ones and then get more complicated.
