The Sewing Loft Blog offers a free pineapple appliqué template, and Craftgossip's sewing section offers a free pineapple hot pad sewing pattern. Each can be scaled up or down depending on the project.
Pineapples can be sewn in varying manners, such as a one-dimensional appliqué or a three-dimensional stuffed object.
Appliqués are one dimensional add-ons to another project, such as a pillow or towel. These can range from very simple to very complex. An appliqué requires only basic sewing skills since it is applied to a piece of fabric before any other modifications, such as stuffing a pillow. Appliqués can also be one piece or several pieces. A multipiece appliqué requires pinning all pieces before sewing to ensure proper placement of appliqué pieces.
A three-dimensional stuffed object requires more sewing skills because of the complicated nature of assembling various pieces correctly. Handsewing skills are also necessary to complete three-dimensional crafted objects since they need to be stuffed and sewing machines can only sew flat seams. Assembling a three-dimensional object also requires more skill than flat machine sewing.
Very few designers of third-party tested pineapple sewing patterns offer free patterns. Investigate community or collaborative sites such as Craftsy or Pinterest to determine if other free patterns are available.
