Learn PatternMaking: Sloper Workshop
This class will guide you through the process of creating a custom fit sloper based on your own measurements.
A sloper is a foundation pattern upon which many clothing designs are based. You can use your sloper to create new patterns AND to alter commercial patterns before sewing.
In this class, we will draft our sloper directly onto muslin to create a fitting dress. We will fine tune the fit, then copy the final sloper onto pattern paper.
Once we have our sloper, we'll cover how to use it to alter a commercial pattern and create your own simple patterns.
Please note: Since this class is very densely packed with information, we do not recommend signing up if you are unable to attend one of the sessions. Each class contains some steps that cannot be made up on your own outside of class.
How this page works...
This is the syllabus for your class! Bookmark or print out this syllabus, as it has important information about supplies, what we are doing each week, and homework (it's fun, I promise!). If you have any questions during the course of the class, please feel free to email me. At the bottom of this page you will find a list of helpful links and PDF's of the materials used in class.
24-30" wide tracing paper
(You can buy a whole roll or pad. You will need 4-5 sheets.) Paper must be see-through. You can find this at Blick in Kenmore Sq, Utrecht in the Symphony Area/Harvard Square, Artist & Craftsman Supply in Central Sq, Cambridge, and other art supply stores. Swedish tracing paper (a tracing paper-fabric hybrid) is also a great option and is available for sale at JP Knit & Stitch.
A pencil & two color felt tip pens (sharpies work great).
2 1/2 - 3* yards of 100% cotton or linen medium weight fabric
In this class, we'll be drawing your pattern right onto the muslin fabric.
*If you are tall, or plan on making a dress that hits lower than the knee, purchase 3 yards.
An L Square or clear grid quilting ruler at least 18" long.
You can also use a 6x24" clear grid quilting ruler, which is available at JP Knit & Stitch.
A square to draw 90 degree angles if you do not have an L square (optional)
Armhole curve and hip curve rules (optional)
Your usual sewing supplies (pins, scissors, measuring tape)
What to expect in each class session
(please read as it contains important information!)
in the first class...
...please come dressed appropriately for taking accurate measurements!
For best results, please wear clothing that is closely fitting but not too tight. Overly tight or loose clothing will result in distorted measurements and require more fitting in the long run. The best thing to wear would be stretch pants or leggings (that are not too tight) and a fitted t-shirt or camisole. Also, be sure to wear whatever style of bra you wear most often. Feel free to bring these clothes to change into.
In this class, we will take all our measurements and begin to draft our bodice patterns.
Materials Needed: All materials except your tracing paper.
Homework: Think about what kind of fitting issues you sometimes run into either with sewing patterns or store bought clothing.
in the second class...
...bring your in-progress pattern draft on fabric. We will finish the bodice in the first half of class.
In the second half of class, we will draft the skirt pattern. Once bodice and skirt are complete, we will add seam allowance, cut them out, and baste together the muslin fitting dress.
Materials Needed: Everything on the materials list except tracing paper.
Homework: Finish basting together your muslin fitting dress.
Sewing Instructions are also available as a PDF download at the bottom of this page.
in the third class...
...bring in your basted fitting dress! In this class we will help each other to adjust the fit of our slopers.
Materials Needed: Your basted fitting dress, marking pens, sewing supplies, and your tracing paper.
Homework: Finish taking apart your dress and copying your dress pattern onto paper if necessary.
in the fourth class...
...we will cover how to use your sloper to alter commercial patterns, as well as a few techniques for creating your own patterns using.
Materials Needed: Your final paper sloper, tracing paper, and a commercial pattern you would like to alter (please come with a pattern whose pieces are already cut out.)
Resources, Links, and Downloads
Here are a few links to hopefully help you along your way in future altering and pattern making!
The method I use to draft the dress is based on the techniques used in Modern Pattern Design by Harriet Pepin and Pattern Making for Fashion Design by Helen Joseph Armstrong.
Modern Pattern Design is VERY retro, so if any of you are interested in 'vintage' style, this book is worth a look. The text can be a little bit outdated (we’ve come a long way, ladies!) but is also a very fun and accessible pattern design method. It is out of print and goes for $100+ on Amazon. However, I have a seen PDF versions (which are often ‘restored’) go for around $20. You can also find the PDF shared online if you dig around. I have scanned the sleeve instructions from this book (download below) in case you are interested in trying out a sleeve.
Pattern Making for Fashion Design is the standard textbook used for pattern making. A new one will run you about $80, but you can also find used copies and earlier editions for a lower price.
If you are interested in pattern making, you should be able to approach most books with the knowledge gained in this class. Let me know if you would like any other book recommendations.
