Drape and draft a basic bodice, skirt, sleeve, and pant pattern block to fit your own body. 


Curious about drafting your own sewing patterns? The best place to start is by creating a sloper, which is a set of basic block patterns that can be used as the foundation for infinite design variations. 

In this weekend intensive course, professional patternmaker Ruby Gertz will guide students through her hybrid method of sloper development that combines flat patternmaking with draping in muslin for the fastest results and most optimal fit. 

Students who attend the course will have a first draft drape of a bodice, skirt, sleeve, and pant pattern by the end of the course. Skills and concepts covered include fit, grainline, ease, basic dart manipulation, seam allowance, pattern trueing, and transferring to paper. 

The course is open to folks of all genders and body types ages 18+.


This process is hands-on and requires collaboration among participants. By signing up for this workshop, you are agreeing to our ground rules of using body neutral language, and asking for consent before touching others. We will dedicate some time at the beginning of class to discussing expectations and group norms in more detail. 


This class meets over one weekend, in person, on Saturday and Sunday from 10am-4:00pm.

The Spokes & Stitches studio is located in Firehouse Arts Germantown, at 5231 Germantown Avenue, B06, Philadelphia, PA 19144 (United States).

There is plenty of free street parking along Germantown Avenue, and the 23 SEPTA bus stops right in front of the building at the corner of Germantown and Bringhurst. There is also a bike rack in front of Tipsy Cafe, next door. We are a half mile walk from the Wister stop on SEPTA regional rail.

Unfortunately, the studio is on the basement level of the building, down a flight of stairs, and not wheelchair accessible.


No. All of the materials you will need are included in your workshop fee (pattern paper, muslin to drape with, C-thru rulers, tracing wheels, pencil). There are also communal tools in the studio (curved rulers, tape measures, scissors, etc.) that you can use throughout the workshop.

A catered lunch will be provided on both Saturday and Sunday, and we’ll do our best to meet all dietary restrictions (let us know when you register if you have any). You are welcome to bring additional snacks if you would like.


Because we will be taking measurements and draping on the body, you will want to wear or bring clothing to change into that is form-fitting. Leggings and a fitted tee shirt or long-sleeve base layer is best. Please avoid camisoles or tank tops, as we want a layer of fabric around your neck and shoulders that we can drape against.


This course will run with a minimum of 4 students, and is capped at 8 students.

Registrations are non-refundable. If you are unable to attend, you may transfer your registration to a friend. Please email with the name and contact info of the person who will be attending in your place, with at least 24 hours notice.


Patternmaking and sewing are different skills, but It is recommended that you have at least basic sewing skills and a basic understanding of sewing patterns before taking this class. If you have never sewn clothing before, or haven’t sewn in a long time but used to, you are still welcome to take the class.
