Written Crochet Pattern Instructions
Schematic
For this design, I wanted to keep the look and placement of the granny squares similar for each size. Each granny square increases the width and length of the garment. For some sizes, we will not need as many granny squares to keep a similar length. Feel free to customize the length of this to be shorter or longer by experimenting with the granny squares and your preferred style. If the front or center back area is too low cut, a half granny square can be created to fill it in.

Make 14 (14, 14, 11, 11) (11, 9, 9, 9) granny squares.
Fasten off and weave in all ends.
Seaming
First, block all the granny squares to dimension. Using a wooden blocking board makes this process easy, and I block each square after making it so it can dry by the time I get the next square done. Using the diagrams from page 4, join the granny squares with either a sl st seam or your preferred seaming method.
Style Tip
- This is the section where we have the option to adjust the length. Work more or fewer rows to adjust length in increments of 4 rows. Note how many rows are crocheted so you can match on the back side later.
Straps
I designed this cover with straps that sit on the edges of the shoulder so the cover can easily be stepped into and slipped over the shoulders.
We will be join our yarn to the top corner of the swim cover. Working into the three center sts, insert your hook into the first stitch, yo and pull up a loop, then do the same to the second and third sts. Three loops are on the hook.
Pull-Up Style
Whether you're relaxing by the pool or exploring the shoreline, this chic swim cover is the perfect accessory for any summer adventure. Designed with a low back and thin straps that sit on the edge of your shoulders, this garment is easy to pull up and down your body without having to go over your head.
Strap Repeats:
Next, yarn over and pull through the first loop on the hook. Then, yarn over and pull through two loops on the hook. Last, yarn over and pull through the remaining two loops on the hook.

We will then pick up stitches again until we have three loops on the hook. Insert your hook into the vertical bar of the second stitch, yo and pull up a loop. Then insert your hook into the vertical bar of the last st, yo and pull up a loop.
With three loops on the hook, repeat the Strap Repeats sections until the strap measures 14-18 inches, trying it on often to get the best custom strap length for the best fit.
Once the strap is the correct length, fasten off and use the tail end to sew the strap to the next corner of this granny square on the back.
Finishing
Weave in any ends, block again if necessary, and enjoy wearing your new swim cover out in the sun.
