    I can’t wait to get started with the Symmes! I know from working on the Willowdale that beautiful bras are possible to create even for the less-experienced sewist. Thank you for your carefully crafted patterns and clear instructions!

    Question: If the main fabric I am using, is there any point to using elastic across the bottom as opposed to bias tape/strip?

    1. Carrie McGowan says:

      Hi! Are you talking about around the bottom of the band? If so, yes because you need stretch in the back band and all fabric has some mechanical stretch that the elastic accommodates as well!

Let me know what you think!
