Go ahead and try the project. Maybe make one out of cheaper fabric until you get it figured out. I usually pin to the right side, bias tape can be homemade or storebought in fabric store, (covers the raw seams), elastic usually is threaded in a folded down fabric area (casing), and I have quilted the inside pockets to give them stability. Study the directions and the diagrams. Often there are general sewing directions that would explain some of your questions. PM me if you think I can answer more of you questions.
