hi Vicki,
I don't really have tips, I just lay the pieces out, sew the squares together, then just lay the pieces back out, sew the squares together, till i have entire strips, then sew strips together. Using a design board to plan the pieces out, or graph paper for large quilt ideas, then the design board to be sure I liked the colors together, I have done 3 round the world tops.
Ones I like doing also are diagonal stripes, very pretty and easy to do. Good luck.
