If you don't want to work with plarn but you do want to make a red, white and blue placemat, then try this cotton crochet pattern from Jessie At Home. This is an easy crochet pattern in that it's worked in single crochet stitches only, but you'll have to do some increasing and decreasing since this crochet pattern is made on the diagonal.
Crochet Patriotic Placemat from Jessie At Home
Red, White, and Blue Plarn Crochet Placemats
Placemats like these would make a fabulous addition to your outdoor picnic table, especially when celebrating holidays like Memorial Day and the 4th of July. They are made with plarn, an interesting material to upcycle for use in crocheting placemats. This free pattern also comes with instructions for complementary plarn coasters.
Note that it's not recommended to use these placemats for hot dishes, but they're ideal when serving sandwiches, salad, pickles, or other similar picnic fares. Best of all, plarn is easy to make (for free) using readily available materials. And of course, you could opt to use different plastic bag colors to make similar crochet placemats without the red, white, and blue theme.
Granny's Scrappy Placemat
My Granny’s series features one round granny squares. This makes it really great for using up those tiny bits of yarn in your stash. If you don't need a placemat, use it as a larger doily. You'll need 282 yards of worsted weight yarn. As a placemat, I recommend cotton since it's more durable, but as a doily, acrylic works too. I used Lily Sugar n Cream for my placemat. Alternatively, I recommend WeCrochet Dishie (cotton) or Red Heart Super Saver (acrylic). I have included instructions to make a variety of sizes depending on your preference. This placemat took me about 8.25 hours to complete.
Patriotic Crochet Dishcloth Pattern
Celebrate the coming patriotic day in an exciting and new way by creating these red, white, and blue color dishcloths. For working on this crochet project, you need Red Heart’s super soft cotton yarn. Furthermore, use an 8.00mm crochet hook with US terminology to make this adorable and theme-based dishcloth for 4th July decorations. Firstly, work on each single color strand separately and then on combinations.
Plarn Coasters
Upcycle plastic bags to create red, white and blue crochet coasters. They also have a matching placemat crochet pattern. This is perfect for a variety of American holidays. The same idea could be used in different colors to make picnic coasters for everyone.
Patriotic Dish Cloth
Fast. Easy. Cute. Can you even GET a better crochet project than that? Oh.. how about beginner friendly?! This dishcloth might just be the best thing you make this week. Pull out some scrap cotton yarn. Hold 2 strands together and work a simple crochet stitch. Changing out one strand of yarn at a time creates a really pretty gradient effect. This looks great in red, white and blue but would also work for other holidays or just as a fun stash busting project!
