Despite the heat and humidity of where I live in Florida, my family and I have been leaning heavily into outdoor activities this summer. 


Beach days, pool days, nature walks, gardening—we’ve ventured outside at nearly every opportunity to stave off any bouts of cabin fever. It’s been the silver lining of quarantine to spend so much time with my husband and our twins, making memories together in the sun and fresh air. If there’s one constant among our various excursions, it’s that we always pack a picnic. But the only issue we’ve encountered is, well, soggy picnic blankets.  

So I took to finding a DIY solution and came up with a picnic blanket that’s Instagram-ready on the top and waterproof on the bottom. It’s a simple sewing project, even for beginners, and I promise that it’ll keep your picnics dry and dreamy.

tools for the project




Measure and mark the desired dimensions of your picnic blanket on the cotton and vinyl fabrics, and then cut them to size with scissors. I made my picnic blanket 52-inches wide by 68-inches long, which fits two adults and two kids comfortably.

Place the right sides of the two fabric pieces together, and pin them in place with straight pins.

Sew around the edges, leaving a one-fourth-inch seam allowance. Be sure to leave at least a five-inch opening on one of the sides.

Using the five-inch opening you left unsewn, turn the fabric right-side out. Push the corners out, too, so that the blanket is flat.

Fold in the raw edges of the five-inch opening, and topstitch it closed. Continue topstitching around all the edges of the blanket to give it a more finished look. Your pretty, waterproof blanket is now ready for a picnic!

We are no strangers to DIY home renovations at Semihandmade. After all, that’s where the idea for making doors for IKEA kitchen systems came from. So naturally, we had to dedicate an entire section of SemiStories to celebrating our design community’s ingenuity, from DIY kitchen ideas to thinking of smaller details like rattan glassware and easy-to-make wall hangings. Don’t just take it from us: we’ve tapped the best in the business. Anita Yokota shared her best trick for a $20 bathroom renovation, Jessica D’Itri Marés shared her favorite spray painter, and Jenna LeBlanc showed us how to give wall-to-wall storage a custom touch. Maybe you’re just dipping your toes in the world of do-it-yourself, in which case we recommend starting small: try your hand at making your own speckled candle holders, for example, or give your greenery an updated home with pretty stacked planters. If you have a handy side (maybe you’ve put together DIY kitchen cabinets or are not afraid to use a power tool), we have projects for you too: painting a hand-painted mural is a fun way to give your favorite room some life or maybe you’re game to try putting together your own TV cabinet like Sarah Sherman Samuel did (PS: she saved thousands in the process). Experts, we’ve got you covered too: from learning to tile and grout your own backsplash to painting your cabinets without a hitch, we have plenty of DIY kitchen renovation ideas to keep you busy. We don’t stop at the kitchen either: from wall-to-wall media centers to fluted doors made for playroom storage, you’ll find ideas to improve every room in the house
