Where: Anywhere, through Zoom.

Cost: $40/ student

Please join Jennifer Stern in a class that will get you really comfortable with your serger and finish a project that’s perfect for the hottest time of the year. A recording will be available to students after the session for review.

This simple A-Line Skirt is the perfect canvas to showcase a few decorative techniques you can achieve using the 3-Thread Flatlock/Reverse Flatlock stitch on your serger. 

The PDF version of the pattern is included with the class. It will be emailed to students. If you would prefer a print version, it will cost $9.99 plus shipping. You can purchase it online here.

In class, we’ll start by customizing the pattern to a length that’s flattering for you. When we cut out the pieces, we’ll cut some sample fabric to practice with first. After perfecting the settings on your serger to get great results with the fabric you picked out to make your skirt, we’ll sew the center front/back seam detail. To make sure the fit is perfect, baste the front and back pieces together for a quick test fit. Then we’ll finish constructing the skirt. Learn how to create an easy waistband and “Not So Blind – Blind Hem”. To finish the skirt, you can add elastic or a drawstring to snug up the waistband. Bonus, this skirt can be worn as a strapless beach cover up too! 

This class has some homework. Before class, please compare your full hip measurement to the garment measurement chart included with the pattern to pick your size. Choose the size closest to your full hip measurement. Trace your size on pattern tracing paper before class.
