Details About Granny Square Bottom Bag
Want to know the best part about this granny square bottom bag? It's the perfect "grab-and-go" size! When finished, your bag will measure approximately 15.7 inches (40 cm) wide and 18 inches (46 cm) tall - roomy enough for your daily essentials but not too bulky.
As for colors, the beauty of this pattern lies in its versatility! While I used a cheerful combination of navy blue as the base, accented with coral red, sunshine yellow, sage green, and sky blue for the chevron stripes - feel free to make it uniquely yours! For inspiration, imagine it in coastal vibes with navy, aqua, white, and sandy beige, or create sunset dreams using purple, peach, pink, and cream. You might also love it in earth tones with olive green, rust, brown, and cream, or try a monochrome magic using different shades of your favorite color.
Remember, the key is to choose a darker shade for the base and body to help hide wear and tear, then let your creativity shine with the stripe combinations!
Recommended Yarn and Crochet Hooks
For this charming granny square bag, I absolutely love using Loopara 5-ply milk cotton yarn - it's my go-to choice for a reason! This yarn is perfect for this project because it maintains its shape beautifully and shows off those intricate stitch patterns in the most gorgeous way. The 5-ply weight creates a sturdy fabric that's not too heavy, while still being soft enough to work with comfortably. Plus, milk cotton yarn has this lovely subtle sheen that makes your finished bag look extra special!
You'll want to gather your colors: a main shade for the base and body (like my choice of navy blue), and your accent colors for those eye-catching chevron stripes (I used coral red, sunshine yellow, sage green, and sky blue). Here's why milk cotton yarn works so wonderfully for this project: it doesn't split while you're working, holds its shape after washing, and the stitch definition is simply stunning.
As for the hook size, I used a 3.0mm hook which creates a nice, tight fabric - perfect for a bag that needs to hold its shape and your belongings securely. This hook size paired with the 5-ply yarn gives you just the right tension for a professional-looking finish. If you tend to crochet tightly, you might want to try a 3.5mm hook, but do a quick tension square first to make sure you're happy with how it looks!

Care and Cleaning Instructions
Daily Care Tips
Keep your handmade treasure looking fresh day after day! Since this bag is made with cotton yarn, it's quite durable - but a little care goes a long way. Avoid setting your bag on rough surfaces that might snag the yarn, and try not to overfill it (those granny squares can stretch!). If you spot any loose threads, don't pull them - simply weave them back in with a crochet hook. A quick brush with a soft clothes brush every now and then will help maintain its lovely texture.
Washing Methods
While our milk cotton yarn is washable, let's be gentle with your handiwork! Hand washing is your best friend here - use cool water and a mild detergent, giving it a gentle squeeze (no wringing or twisting, please!). Never soak it for too long, and avoid using bleach or harsh chemicals. After washing, reshape your bag while it's damp, paying special attention to the granny square bottom, and lay it flat to dry away from direct sunlight. Your bag will thank you by staying beautiful longer.
Storage Suggestions
When your bag needs a rest, store it with the care it deserves! Stuff it with acid-free tissue paper to help maintain its shape and prevent creasing. Keep it in a cool, dry place away from direct sunlight (which can fade those gorgeous colors). If you're storing it for a longer period, place it in a breathable cotton bag rather than a plastic one - your crochet work needs to breathe! And here's a pro tip: avoid hanging your bag by its straps during storage, as this can cause stretching. Instead, lay it flat or stand it upright, just like you'd display it.
