I did my first quilt using the "Rag Quilt" pattern. Love it as you quilt as you go and can make it as big as you want.
I did 3 of them. 2 in flannel.
Then I tried paper piecing and did a lap size quilt.
Use cheaper material to practice one block. ( You can get enough variety of blocks together one day to use up in a table runner or tote bag.) Each quilt I do is something new for me and becomes a challenge.
Good luck and have fun!
