For a novice it may well take considerably longer. If you have never quilted or are not sure of your needlework abilities start with a smaller project, a cushion or a wall-hanging.
Many bookstores carry inexpensive books of Hawaiian pillow patterns.
On-line, both Amazon. PBS has a sampler collection of pillow patterns available through its Hawaiian Quilting television series. These books contain simplified instructions or the following instructions may be modified for smaller items. If you decide to continue, by all means join a quilt club. The help, encouragement and support you receive from other quilters will be a most valuable asset.
