    Two Color Treble Crochet Shell Border
    Kathryn Vercillo

    This free crochet edging pattern creates a decorative ruffled edge worked in two different colors. It is perfect for baby blankets, but it can also be used on any other project where you want a distinctive border. Work it as a single row across one edge of a project (such as a pillowcase) or all the way around the border of a square / rectangular design as shown in the instructions.

    Materials for Two-Color Crochet Border

    Yarn and Double Crochet
    Kathryn Vercillo

    This crochet border requires that you have a project that needs an edging, two colors of yarn, and a crochet hook.

    The yarn should be the same weight as the yarn used in the body of the project; amounts vary depending on the size of your project. The two colors should complement each other as well as the color used in the main project. The crochet hook should be the same size as that used in the project, a size suited to the weight of the yarn.

    The example in this project is a small double crochet...MORE project, two colors of worsted weight yarn, and a size H crochet hook.

    Join Yarn and Begin Border

    Join Yarn in Corner for Border
    Kathryn Vercillo

    Join yarn in the first stitch of the row, at the top right corner if you're right-handed. Chain 3, which counts as a double crochet.

    Note: Your corners for this project will consist of the following stitches - sc, hdc, dc, hdc, sc. As you will see when we get to the next corner, they may all be worked in the same stitch or they may span 2 to 3 stitches around the corner. This adjustment is made because each crochet project will have different lengths. We begin here with a dc, which is the...MORE middle of the first corner.

    Create Your First Full Corner

    Corner for Treble Crochet Border
    Kathryn Vercillo

    It is time to create your first corner. If you have already reached the corner stitch, then you will work the following all into the corner: sc, hdc, dc, hdc, sc.

    In many cases, the count doesn't work out perfectly, so you will need to cheat your corners a little bit. That's totally okay. The best way to cheat the corner is to single crochet to the corner after your final treble crochet shell. In other words, end the row with a treble crochet and as many single crochet stitches as it...MORE takes to get to the corner, whether that's more or fewer than the 5 sc you would normally have after a treble crochet shell.

    The other option is to extend the corner over a few stitches, working the five stitches ( sc, hdc, dc, hdc, sc) across 2-3 stitches around the corner. Play around with the options to see what you prefer.

    Row 1, Side 2 of Treble Crochet Border

    Kathryn Vercillo

    Once you've created your first corner, you will repeat step 7 across side 2. Our example has a short border, so it's just 5 sc, 1 treble crochet shell, 5 single crochet and we're already at our next corner. Blankets and other long projects will, of course, have many more repeats of the pattern.

    Finish Your Starting Corner for Round 1

    Treble Crochet Shell Border
    Kathryn Vercillo

    The last thing that you need to do for round 1 is to complete the final corner, which you began in Step 3. This corner, like all of the others, will consist of sc, hdc, dc, hdc, sc. However, you already completed the last half of that, so all that you need to do now is crochet sc, hdc then slip stitch to the top of the dc to close the round. Finish off and weave in ends.

    Single Crochet Around Shell

    Single Crochet Around Shell
    Kathryn Vercillo

    Single crochet in each stitch until you reach the third stitch of the next set of 5 sc. (In most cases, this is going to be ten single crochet stitches in a row. However, because of the possibility of "cheating your corners" it may not always be ten stitches. It is most important to always place the treble crochet shells of round 2 in between those of round 1. The exact number of single crochet stitches in between them is less important.) Work this pattern across the row until you reach...MORE your corner.
