Instructables are tutorials added to the site by users and will show you how to make just about anything. You can save your favourite crafts and create your own instructable for anything from drawing a cat to baking chocolate cake. Here are some instructables I like:
Harry Potter magic wand made from paper, glue and paint.
A picnic blanket with a lit perspex center to act as a little table.
A lamp made from paper.
Feel free to post a link to your favourite instructables in the comments!
