The tools that put Christmas into the quilting itself rather than the fabric. Ruler templates for stitching holly, snowflakes, and stars into your quilting lines, seasonal appliqué frames, and a handful of small pieces — zippers, pins, hardware — in colors that suit the projects you're making this time of year.
Ruler templates come in shank-height and long-arm versions, so check which fits your machine before ordering; the size is listed on each product page. These aren't seasonal in the sense of getting packed away — a snowflake motif quilts beautifully on anything wintry, and the templates last for years.
