I agree with Murphy, go to a beginners class and take a rail fence pattern" or something Local quilt shop recomnmends. Some of the beginners classes try to teach everything all at once. they usually are different blocks then put together. You end up with a sampler quilt. I think that is too much to start with, try going for only 1 pattern in lap of twin size. See if you are going to like the process. Buy quality fabrics at LQS not a discount store to start with. Cost it more but if you start small it won't be that much( it will be easier to sew etc).
I started out with rail fence class and I'm glad I did. I took my friend to the Sampler Quilt class for beginners. Some of those blocks were difficult for me after 3yrs. Friend never has finished and does not quilt now. Let us know how you do Welcome
