If you have never heard of Spandex, well Spandex is an elastic synthetic fiber, also famously known as Lycra. It is much stronger and a lot more durable than natural fiber.

This elastane fabric is made of natural and synthetic fibers to provide the stretch and recovery that you need in any crochet project that you intend to get wet in.

Cool right! That’s why this is so important to look for the best stretchable yarns with elastane to maintain the shape and provide that extra stretch.

But remember not all spandex yarn works the same. It would have to be lightweight preferably below a category 3 like a DK or fingering yarn.

Plus it should also be either cotton or microfiber. Now, where can I find these yarns you might ask?

Well before we get there, why don’t you have a look at a few of my favorite Free Crochet patterns here:

Best Yarns for Crochet Bikinis and Swimsuit

Cascade Fixation Yarns


cascade fixation yarn

Cascade Fixation: Personally I prefer Cascade Fixation yarns and have been using them for years!

They are inexpensive yarns and are easily available here in the States. I usually get mine directly from the seller (in bulk) or you can also find them on Amazon and on Etsy. It is a DK weight cotton yarn and I would normally use a 2.0 – 2.5mm crochet hook.

Another great thing about this yarn is that it dries fast, doesn’t shrink, does not color bleed, and best of all comes in a variety of solid and splash colors! Read more about what I like about cascade fixation yarns here

Alize Diva Stretch



Alize Diva Stretch: I only recently started using this yarn because they are usually shipped from Europe and take a while to deliver. (For those of you living in Europe this is a great option ie cheaper shipping!) 

And of course, you can find them on Amazon and Etsy which is fantastic! This yarn quickly became one of my favorite yarns to use for summer.

It is a lightweight microfiber acrylic yarn with elastane and the best hook to use would be 1.5mm2.0mm. Alternatively, you can also double up the yarn and use a bigger hook size.

This yarn is extremely stretchy and you would need some getting used to it. It is also quick-drying, with plenty of gorgeous colors and did I mention super stretchy?! LOL.

Another great amazing thing about this yarn is that it has a sheer finish just like a regular swimsuit.

So if you are used to working with a thinner yarn, then this is your perfect match!

Nako Comfort Stretch


Naki comfort stretch

Nako Comfort Stretch: This yarn is very similar to Alize Diva Stretch too. Its composition includes microfiber acrylic with a touch of polyester. It is also a lightweight yarn and super stretchy.

The best hook to use would also be between 1.5mm2.0mm. I’ve only used them once and since I find them closely similar to the Alize yarn and not easily accessible here where I like, I prefer to stick with Alize Diva instead.

Although these are not readily available here in the States, however, you can find them on Etsy and eBay as well. And if you’re living in Europe, then you’re in luck again!
