Hi, do you have any idea in mind what you want to make? Either a traditional pattern you'd like to try or a particular purpose for your quilt?
It's surprising how different making a quilt by hand is to making it by machine, you may like one and dislike the other, or prefer one for some stages of the process and the other for other stages of the process.
Myself, I've not come across any beginner classes in hand piecing and quilting, only machine ones, however, all the machine classes, allow you to borrow a machine, usually reserved in advance, requiring a deposit etc. The problem with this, is it's often not possible to finish the project in the class time, which leaves you stuck as to how to finish the project.
It's true that machines can often be got hold of very cheaply at thrift stores or garage sales, the problem is, if you are not at all familiar with sewing machines, that you may struggle to get it set up correctly and it may not behave as the instructions (if you even have them!) suggest it should. If you can't get it set up right, you may get a very unsatisfactory result.
Cheers Anne
