Pattern Notes

• This Pattern Uses Standard US Terminology.

• 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.

Written Crochet Pattern Instructions

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.

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.

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.

Crocheting lightweight and airy garments is a fabulous way to add a delightful blend of style and comfort to your summer wardrobe.
