Moroccan Tile Stitch

This stitch, when worked in the round, starts with any multiple of 3 sts. For demonstration purposes, I'm working it into a row of foundation single crochet, but it can be worked into a chain or into any series of sts, as long as it's a multiple of 3. You can start each round with a Chainless Starting Double Crochet (CSDC)/Standing Double Crochet (STDC) *or* a chain 3 — it's up to you.

Round 1: With Color A, CSDC (Alternate: ch 3), ch 1, dc in the first st (V st made). *Skip 2 sts, [dc, ch 1, dc] in the next st. Repeat from * until 2 sts remain. Join to CSDC (or top of ch 3) with a sl st. Remove the hook from the active loop and place a stitch marker in the loop to secure it, so it won't pull out as you work the other color.

Round 2: With Color B, STDC (Alternate: join with sl st and ch 3) in ch sp of 1st V st of previous round. Ch 1, dc in the same ch sp (V st made). [Dc, ch 1, dc] in each ch sp around. Pull active loop and working yarn of Color A to front of fabric, then join with sl st to STDC (or top of ch 3). Remove hook from loop, place marker in loop so it doesn't pull out.

Round 3: Replace hook in active loop of Color A, CSDC or ch 3, ch 1, dc between first and last V of the row before the previous round (NOT in the ch sp, but between the Vs). [Dc, ch 1, dc] between the V sts of round before the previous round around, enclosing previous round. Leaving working yarn and active loop of Color B behind fabric, join with sl st to CSDC. Remove hook from loop, PM in loop so it doesn't pull out.

Round 4: Insert hook in the ch sp of the first V st of the previous round. Replace hook in active loop of Color B and pull it through the V to the front, leaving working yarn behind. CSDC, ch 1, dc in the ch sp of that first V. [Dc, ch 1, dc] in each ch sp around. Pull active loop and working yarn of Color A to front of fabric, then join with sl st to CSDC. Remove hook from loop, PM in loop so it doesn't pull out.

Continue repeating rounds 3 and 4 until you're done, and then finish off with an odd numbered row. There are two patterns using this version of the stitch here on Moogly, and at least one more on the way! I hope you've enjoyed this tutorial, as well as the patterns. And if there's another tutorial you're looking for, please do let me know!
