About Xochil Herrera: The Chicago Pattern Maker

Xochil Herrera provides professional product development, pattern making and fashion design services to brand clients and businesses throughout the US, and is based in the Chicago area.

The Chicago Pattern Maker was founded in 2009, and collaborates with brands and factory partners, bringing technical expertise, guidance, and genuine care to the pre-production process of technical design, pattern development, and prototyping.

As an analytic creative, Xochil works hard to create beautiful and functional products ready for market. Xochil is a detail oriented, results driven task master, and enjoys the technical creation process, making products come to life through strategic sourcing and prototyping with a "design to manufacture" approach.

Xochil has collaborated with numerous brands and designers to bring their concepts from idea to reality. She has a strong skill set in technical design, pattern making, material sourcing and prototype development with production in mind. She has a keen understanding of the manufacturing process through working with various factories, training and using industrial equipment, and being closely involved with clients throughout product development. Her background in tailoring and being a lifelong sewer has helped shape her skills in garment fit and construction techniques.

Specializing in pattern making for both knit and woven materials, Xochil and the TCPM team work across multiple apparel categories, from contemporary "ready-to-wear" to more complex technical pieces including outerwear, functional workwear, plus size or extended sizing, and soft goods accessories. She has extensive experience in athletic active wear and performance apparel for men and women, including swim and undergarments. Xochil enjoys learning about innovative materials and applying them to new designs.

Xochil is currently serving as Secretary on the Board of Directors for the Apparel Industry Board Inc.

Melissa Petersen

Melissa Petersen

Melissa Petersen has been working as a Technical Design Assistant at the Chicago Pattern Maker since 2023. She graduated from Columbia College Chicago in 2017 with a Bachelor of Fine Arts in Fashion Design and a minor in Business.

Her senior thesis collection focused on textile prints and embellishment, which after graduation helped her land a role working as a designer for a textile and garment components company after graduation. While in this position, she designed and coordinated the company's bi-annual print collections, working closely with an international team each season to produce this and many other garment component product collections.

Melissa has also previously worked in various positions as a seamstress, as well as interned for several Chicago-based clothing designers. She has been sewing since she was 14 years old, and her experience with and knowledge of garment construction greatly helps her in her current position as a technical design assistant, creating technical flats and putting together tech packs, sewing prototypes, and working through fit revisions to make sure each product fits exactly as it should. She is enthusiastic to work for TCPM and loves being able to utilize her talents and skills while working with clients to help them bring their product ideas to life.

Violet Velazquez is a Chicago-based designer whose work bridges technical craftsmanship and artistic storytelling. She graduated from Columbia College Chicago in 2017 with a Bachelor of Fine Arts in Fashion Design and a minor in Business.

Violet currently works as a design assistant at the Chicago Pattern Maker, where she contributes to product development across multiple stages of the design process. Her work includes developing technical sketches, sourcing materials, and assisting in sample creation, allowing her to refine both her technical expertise and understanding of garment construction.

In addition to her technical work, Violet has gained experience behind the scenes at major fashion events, assisting designer Emily Sifrit of Ekaye Collection during New York Fashion Week and Miami Swim Week. During these shows, she supported model fittings, dressed models backstage on show days, and assisted with sewing final garment details to ensure each look was runway-ready.

At the core of Violet’s practice is the belief that fashion is a powerful form of personal expression. She views clothing as an art form we live our lives in, capable of shaping identity, confidence, and imagination. Inspired by music, creative culture, and the world around her, Violet approaches design as a space where storytelling and craftsmanship meet.
