This workshop was TERRIFIC right from the start to achieve a nicely fitting swimsuit top. Heather was practically holding my hand through the entire process. The explanations were easy to understand and the videography was excellent as well. A beginner could easily be successful using this workshop to make a swimsuit. When I had a question, Heather took the time to respond and the answer was beyond my expectation...clear, concise and detailed! I love that I can log in and watch again and again. Heather has a fresh approach to sewing instruction that IMO matches all skill levels and is superb for the newest among sewists.

I made my first swimsuit using this course. I was pretty nervous about swimwear, especially putting in an underwire, but the course made it so easy to understand. Heather Lou was so personable, and I loved that it felt like she was sewing right along with me! I'm super proud of my finished swimsuit, and I've gotten a ton of compliments on it!

I absolutely loved the accompanying video tutorial for the Sophie Swimsuit pattern. I wish that all sewing patterns came with a video option...I barely looked at the written instructions while sewing up my swimsuit because having a video guide + heather's teaching style made the whole process so simple. And it was like having a personal sewing date with Heather in my lounge room! Being a visual learner, a video tutorial is definitely my preferred method of sewing instruction and I can't wait to see the next one.

Q: What will I need to get started?

A: Before you get started, we’ll share a complete supply list, along with information about where and how to source everything on said list.

For an underwired suit you'll also need underwires, channelling, bra lining and bra cup foam.

Q: How long does the course take to complete?

A: It’s up to you! To give you an idea of how long the course is start to finish, the video runs around 4 hours long and comprises 11 lessons total. Binge watch them in a weekend, or do a little at a time. You can return to the course as many times as you’d like, and there’s no time limit for you to complete in.

A: Once you enroll in the course, you’ll receive a PDF copy of the Sophie Swimsuit Pattern. Head to the “Materials & Resuources” session to download it to your device of choice.

Q: What if I want a printed pattern?

A: The Sophie Swimsuit is only available as a PDF, although we include copy shop files if you'd like to save yourself some cutting and taping.

Q: How long can I access the course?

A: All day, ‘erryday. But for real, this course includes lifetime access. After you enroll, the course is yours, which means you’ve got unlimited access for as long as you like, across all devices for all of eternity.
