The projects of images are so easy to do and you only thing common things to make them, like, for example a plastic card, clothes-pins or wires.
The first DIY is how to make a tool that spreads glue, and for this, it is used a plastic card. The second project is about cutting pipes, using only metallic wire. For the third project, you have to check the video.
The ideas are amazing and what is even better is that all tools ready to hand.
