Twin sisters Lyndsay Lamb and Leslie Davis give their all to every home they refurbish together on HGTV's Unsellable Houses — especially their hardworking attitudes and creative ideas. While renovating their way through real estate in Snohomish, Washington, they've mastered the art of do-it-yourself projects. Now, they can find a cleverly-cool solution to any home design equation. Ahead, find their best DIY home projects from Season 4 of Unsellable Houses. Warning: You might just want to try some of these out at home.

The Feather Ballroom, Presented by Lamb and Co., is a historic wedding and event venue located in downtown Snohomish. During Season 4, the twins spruced up the property with a few DIYs — one of which was a DIY letterboard crafted by Owen Mather, the renovation director of Lamb Renovations.

How They DIYed It: The wood-slat board is handmade with slim, black-painted shelves to hold clear, store-bought block letters. The result is a warmer, more rustic take on today's traditional letter boards.

Another clever Feather Ballroom design: Simple floating shelves that evoke a speakeasy ambiance.

How They DIYed It: The team mounted unstained slabs of wood onto a deep-green-colored wall for maximum contrast. Vintage-look bottle openers hang below from rustic hooks, while a natural palette of label-less glass bottles and bold shelving brackets offer a cozy-industrial feel.

Leaning into this cottage's “micro, wild-and-free” aesthetic (as Lyndsay put it), the twins crafted a wall-mounted spice shelf and storage rack. “It’s a small space, so that’s where the micro comes in," said Lyndsay. "And then wild and free: fun colors, fun design, lots of different patterns. We want it to feel very free-spirited.”

How They DIYed It: Though similar spice racks exist online, Lyndsay and Leslie brought this one to life using slim pieces of cut-down wood affixed with nails for a fraction of the cost. They stuck to a natural finish, but the shelf could be stained to better fit any aesthetic.
