Hi! I’m Ellie Lum

I’m a maker and a teacher. I started Klum House because I love encouraging and inspiring people by teaching sewing tips & tricks through fun, hands-on workshops. With clear instructions and 20 years experience, I will teach you how to make wares that look like they came off the shelves of your favorite handcrafted goods shop!

Ellie’s Story

In 1998, Ellie co-founded  R.E. Load Bags, a custom messenger bag company, which set the standard for many other companies that make custom bags. Over the years, she fell in love with teaching industrial sewing through training folks to make bags for R.E. Load. Ellie saw how those skills opened up a trainee’s creative potential and formed a foundation that could be continually built on.

Ellie went onto start Klum House in 2015, born out of the desire to share professional bag making skills with everyone. Klum House now boasts an in-house bag pattern & kit line, as well as a collaborative making studio and creative education space where local artists & maker share their skills.

Ellie is such an encouraging teacher and clear as a bell in her instruction. She broke complex information down into understandable bits, and explained the why's as much as the how's.
