A stitch in time saves nine, but a stitch in a parachute saves lives. Piece together sturdy seams with today's Groupon: for $25, you get $40 toward a sewing, quilting, or embroidery class and $10 toward supplies and materials at Kramer's Sew & Vac.

Kramer's stacks its schedule with a slew of quilting, sewing, and embroidery classes that illuminate fundamental skills and advanced seamstressing styles. Sewing Machine Basics opens up thimble un-nimble minds to precise stitching techniques on motorized equipment ($50), and Basic Sewing Project classes guide students through easy-to-follow steps to construct a tablecloth or emblazon an intimidating standard onto a tall-ship sail ($30). Clutter Bug Bag attendees craft a small sack perfect for carrying cosmetics, prescriptions, or baby kangaroos ($40), and the Quarter Square Log Cabin course leads needleworkers in constructing quilt tops ($40). The shop also hosts more advanced classes in quilting as well as sessions devoted to embroidery and re-inflating popped pincushions.

Many of Kramer's classes require supplies such as thread and scissors, which generally cost $10–$20 for students who do not bring their own. Groupon customers can use the store's sewing machines for free as long as they reserve them in advance, or students can bring their own sewing machine or pocket Rumpelstiltskin from home.
