Struggling With Fit?

We understand the challenges when sewing garments and facing fitting issues. Our Master Pattern Kits provide fully graded patterns and an illustrated guide for creating a customized sloper. Access our free learning center tab and customer support anytime for assistance.

Following the completion of your sloper, your instruction book will guide you as you convert your sloper to a muslin mock up to test your fit. Once you have this completed, this will be the foundation for any finished garment you create. Additional instruction is available in our online learning center, and our online academy.
