How hard for a begginer to make a twin size blocks quilt?

Both of these ladies are right and have given you some great information. This will be a very easy quilt to piece. You should have a plan for the layout, so that no squares of the same fabric are next to each other. If you shop around you should be able to find nice fabric and still stay within your budget. This should be easy to quilt too, but if you don't know anything about quilting (sandwiching together the top, batting and backing, plus binding the edges) you will need to learn something about that. You'll have to decide if you want to machine quilt it, hand quilt it, tie it, or pay someone else to quilt it. Go to the websites they have recommended, check out books from the library, and ask other quilters. You might find help from local quilt shops and quilt guilds. I have a king-size quilt made from 5" blocks, and I love it. Good luck.
