Take a look at the coaster tutorial. While the tutorial is quite easy and probably a beginner level, it still presents an interesting working opportunity for advanced workers as well. The design is quite appealing.
I believe that the majority of you are going to like it. AS the guidelines tend to be easy to understand I also think that there will be no problems while creating this coaster whatsoever. The coasters are very useful and the technique learned in this tutorial can be also used to create some of the other, maybe even more sophisticated projects. Have fun and let’s start crocheting already.
