Layered Edge Slip Stitch Seam

The layered edge slip stitch seam provides a neat and tidy edge when joining two solid blocks together. You may also see this called slip stitch seam. It is created by working slip stitches through the back loops of the stitches of both blocks at the same time. You will stack one block on top of the other in order to work through them at the same time. The video below tells you which side to have on top, or which to work through first, but you can actually go through either one first. Just be sure to continue to work in the same way across the entire seam.

Note: Crochet does not have standardized naming conventions for special stitches or all techniques. Designers may call stitches by whatever name they prefer. For this reason, it is difficult to search online for how a particular special stitch is created. Another reason it is hard to find the “correct” way to work a particular special stitch is because each designer might work a special stitch in their own unique way.

Arrange 2 squares on a flat surface having the side edges that are to be seamed adjacent to each other and having one piece below the other piece. Using the yarn color of the lower square and leaving a 5-inch beginning yarn tail, make a slip knot and place it on the hook, with the working yarn under the edges to be seamed beginning at the right side edge. Insert hook from right side to wrong side in the back loop of the first stitch of the lower piece, then insert the hook from right side to wrong side in the front loop (when the loops are oriented toward you this appears to be the back loop of the square) of the first stitch of the upper square, yarn over, and pull up through to the right side of the work and through all loops on the hook to complete the first stitch as a slip stitch.

[Insert the hook in the back loop of the next stitch of the lower square and in the front loop of the upper square, yarn over, pull the loop up through the loop on the hook to complete as a slip stitch] repeat working in the corresponding loops of the stitches across the squares, ending the last slip stitch in the last stitch at the corner at the opposite (left side) edge of the squares. Fasten off, leaving a 5-inch yarn tail.
