From crochet.about.com - Openwork Black Lace Edging Free Pattern

A Design by Sandi Marshall

This crocheted lace edging has an openwork design, alternating with solid triangle shapes. The areas that are crocheted in one loop only form a line of remaining loops on the right side of the piece (the remaining loops can simply be decorative but are also used for adding optional embellishment if you choose to add the decorative extras I've designed for this pattern).

Materials Used In The Example: Worsted weight yarn - color Black
Hook: US Size G crochet hook

Finished Size, when made with materials above: 4 inches high. The length will be determined by you.

Alternate Materials: For a narrower edging, you may prefer to use thread.
Size 10 thread with a US Size 7 or 8 steel crochet hook is a popular thread choice.
Finished Size, when made with size 10 thread and a US size 7 steel hook: 1 1/2 inches wide

Abbreviations: ch = chain, chs = chains, dc = double crochet, ea = each
sc = single crochet, sp = space, sl st = slip stitch

How To Slip Stitch (sl st) = Insert hook in stitch, wrap yarn over hook, pull yarn through the stitch and through the loop on the hook, at the same time. A slip stitch does not add any height and is used to join a chain or stitch to another place in the crochet piece.

Starting Chain: Chain a multiple of 11, plus 10. "Multiple Of" Explained: http://crochet.about.com/od/learnbasics/qt/multiple.htm

With the addition of orange trim along the bottom edge, this makes a great Halloween edging. There are also instructions for adding an optional ghost outline to the solid part of the edging, if you wish to. Orange Trim and Ghost Instructions: http://crochet.about.com/od/halloween/ss/ghostedg.htm
