I baste the pieces with a running stitch and then baste the pocket on and the boot and the hat and then sew the whole thing onto the fabric with the sewing machine. It's not hard. It's like hemming a cuff.
By the way I used to ride to college with a friend who drove a 69 or so VW or slugbug! My husband and I also listened to 8 tracks and My DH also collects all the differant turntables and LPs and 45s and yes 8 tracks and we have an 8 track player. I have 4 6' shelves full of records and players etc.
