The Crochet Penelope Bottom is full of joy and built to last! Each stitch uses basic stitches you already know and love, like the single crochet and half double crochet.

I’m using a water-approved yarn by Cascade Fixation that’s not only perfect for swimming but comfortable and soft to be worn all day long. It’s a cotton yarn blend with spandex fiber, making it the ultimate summer yarn. 

I am also using a 3.0 mm crochet hook, which will create nice snug stitches that hold everything securely in place.

This sport weight yarn is not just stretchy and comfy, it’s tough too! You can splash around, or catch some rays without worrying about your crochet sagging or stretching in any way.

And because comfort is key at the beach, this Penelope Bottom offers a stretchy elastic band along the hips and leg openings.

The band will gently hug your curves in all the right places, ensuring you stay comfortable and confident all summer long. 

Plus you won’t even need a lining for this one, although you’re always welcome to add one in if it gives you extra peace of mind

Also, feel free to add your own personal touch. 


Adjustability and Comfort

Making your own bikini should be a blast, and feeling amazing in it is even better! This pattern is all about creating a swimsuit that looks fantastic and lets you feel comfortable and confident all day long.

How to Care for your Crochet bikini wear

crochet penelope bikini bottom

To care for your crochet swimwear and keep it looking great, it’s essential to follow a few simple steps.

Firstly, always hand wash your crochet swimwear in cold water with a mild detergent to help preserve the delicate fibers and stitches. Avoid using bleach or harsh chemicals, as they can damage the fabric and cause it to lose its shape and color.

After washing, gently squeeze out excess water and avoid wringing or twisting the garment, as this can cause the crochet stitches to stretch or distort.

Lay your crochet flat to dry in a shaded area, away from direct sunlight, to prevent fading and ensure that it retains its shape.

To prevent snagging or tearing, store your crochet bikini wear in a cool, dry place, away from sharp objects or rough surfaces.

If you need to pack it for a trip, place it in a soft bag or pouch to protect it during transportation.

By following these care instructions, you can extend the lifespan of your crochet wearables and continue to enjoy them for many summer seasons to come.
