Since this is going to be your first, I would strongly recommend that you make another pineapple block (scraps or matching your runner) and create a practice sandwich. You can audition your thread choice, verify your needle size (top stitch or jeans needle should work well), work out any tension issues, and most importantly do a bit of practice before you work on your actual project. Even straight stitching with a walking foot takes a bit of finesse and it's better to not practice on such an important item!
