I do wish you well with this lovely craft - it is so enjoyable. Word of advice - if you are planning to recycle some old curtains and duvet covers into a quilt, do make sure that the fabrics are similar (e.g. all polycotton) and of the same weight and thickness or things will go seriously awry.
There is something to be said for your first project being a kit - even if it is just a small thing like a cushion cover. It gets you into it and gives you guidance step by step through your first effort, and then it is easier to branch out on your own a bit.
I started with a quilt for my the baby GD, then another for an older GD. Now working on a kingsize quilt for my DD - but it has been on hold as I have not been well.
www.favequilts.com - Favequilts is a good site and they send out daily patterns and ideas to your email if you so choose.
When you get into your own efforts, rather than a kit, try easy patterns first - e.g. log cabin, or disappearing squares or simple blocks - you can add interest to this by careful choice of colour and layout.
There are lots of tutorials online where you can follow a video that shows you how to do all sorts of things: sewing on a binding, fastening the lining/backing etc. Try these: gourmetquilters.com; www.howtoquilt.com; there are lots. Go on to YouTube and type in beginner quilting or some such and you will be inundated!
