Level of skill required
While these designs are very easy to sew the patterns and instructions assume that you already know how to sew. They will not teach a learner the explicit (easily taught and learned) and tacit knowledge (experiences that are not easy to explain) required to be a competent stitcher.
This is not to discourage learners as you will certainly learn from experience but it may be a costly and time consuming process. I firmly recommend taking sewing lessons:- at your school or through a community college
- from a friend or relative.
If this option is not available there are several books that I recommend you buy or borrow:
There are also lots of online resources as well:
