Hello, Diana! I fairly appreciate your ideas and I am glad to answer your question.
If you want to record all the steps of making handiwork, it’s an ideal choice to record them by a digital camcorder. But you can also do it with a screen recording tool instead of a camcorder. Currently, there are lots of applications that can be used for recording screen activity on computer screen or in front of camera, that is, you should get a good screen recording software that can record video through web cam.

As far as I know, Camtasia is the best powerful screen recorder around the world that can capture screen, video camera and voice as well. But it comes with $ 299. Apart from these expensive software, I think it’s smart to choose a screen recorder offering good recording results with low charge.
So I strongly recommend Apowersoft Free Online Screen Recorder to you because it provides two ways to record web cam and you have the ability to make your own videos flexibly. Moreover, it can export videos with decent quality, even better, it’s free.
This screen recorder has an intuitive interface, so users to handle it in no time. That’s why I won’t illustrate how to use it in details. Here is a demo video about how to make an educational video for you and I think you can get more clearly understood after you watch it.
Audiences particularly like videos with proper commentary, and it’s better to make educational videos with voiceover to demonstrate brief instructions. Before recording, you should choose Microphone as your audio input mode.

After you finish your video, you can make a trim and crop of your recording videos by Windows Live Movie Maker. This free software from Microsoft can help you polish your videos, which will make your videos more professional.
Hope it can help you. Feel free to ask me, any time.
