i would say if you can follow barb_mo's directions on her tute and you can sew straight lines then there is no problem doing it...
its sewing strip after strip... recutting the sewn strips... and then sewing them together again.. pinning helped me and that 1/4 in. seam allowance.. i am self taught with no classes behind me.. if the directions are good.. i can usually pull it out on a beginner/intermed. level... this pattern falls in that category with ease... pluse you have help with any questions from anyone doing one with barb.
