Foundation single crochet

A chainless foundation makes the starting chain and the first row of single crochet (UK double crochet) at the same time. Each foundation single crochet, written fsc, is one chain with one stitch standing on it, and the next one starts in that chain. The finished foundation row stretches more than a plain chain does.

How to work it

  1. Chain 2 and pull up a loop

    Start with a slip knot on the hook and chain 2. Push the hook into the second chain from the hook, which is the first chain you made. Take the yarn over the hook and pull up a loop. There are two loops on the hook.

  2. Make the chain at the foot

    Take the yarn over the hook and draw it through the first loop on the hook only. There are still two loops on the hook. That one pull made a chain stitch, and it is the foot of the stitch you are making.

  3. Finish the single crochet

    Take the yarn over the hook and draw it through both loops. One loop is left on the hook. That is one foundation single crochet: a chain at its foot and a single crochet standing on the chain.

  4. Find the chain at the foot

    Two foundation single crochet stitches, seen as they hang from the hook: the strip grows upward, with a chain at the foot of each stitch along its left edge and the tops of the stitches along its right edge. The chain at the foot of the last stitch is ringed.

    Look at the stitch you just made. The loop on the hook is at its top. The chain you made in step 2 is at the other end of it, on the far edge of the strip from the hook. Seen from the edge it is two strands that lie side by side like a V. The next stitch starts there.

  5. Start the next stitch in that chain

    The hook lies across the front of the last stitch and passes under both strands of the chain at its foot; the head of the hook shows beyond the left edge of the strip. One loop is on the hook.

    Push the hook under both strands of that chain. Take the yarn over and pull up a loop: two loops on the hook. Take the yarn over and draw it through one loop to make the new chain. Take the yarn over and draw it through both loops to finish the single crochet.

  6. Repeat to the width you need

    Three foundation single crochet stitches laid flat with their tops up: a chain runs along the bottom and a single crochet stands on each chain. The last one made is at the left, under the hook.

    Work step 5 again for every further stitch, each time into the chain at the foot of the stitch before. Make one foundation single crochet for each stitch the first row needs. Then turn and work the second row into the tops of the stitches, as on any row of single crochet.

How many to make
One for each stitch of the first row

A starting chain is easy to make tighter than the rows that follow, and then the bottom edge pulls in. In a foundation row every chain is made as part of a stitch, so the edge comes out at the same size as the stitches and gives with them.

To use it in a pattern that starts with a chain and a row of single crochet, count the stitches of row 1, not the chains. If the pattern chains 21 and works 20 single crochet into the chain, make 20 foundation single crochet and go straight on to row 2.

The same plan works for taller stitches: a half double crochet (UK half treble) or a double crochet (UK treble) can stand on the chain in place of the single crochet. Each has a page of its own.

When it goes wrong

I cannot see where the next stitch goes.
It goes into the chain at the foot of the stitch you just finished, not into its top. Look for the V at the bottom of that stitch, on the edge away from the loop on the hook, and push the hook under both strands of it.
My strip has no chain along the bottom.
The pull through one loop was left out. After you pull up the loop, the yarn goes over the hook and through one loop first. Only then does it go through both.
My row came out too short.
Add more. Work further foundation stitches onto the end of the row, one at a time, until it is wide enough.

Left-handed

The pictures show the hook held in the right hand. For the left hand, read each picture as its mirror image.

Variations

  • Foundation half double crochet. The same chain at the foot, with a half double crochet on it. Use it when the first row of the pattern is half double crochet.
  • Foundation double crochet. The same chain at the foot, with a double crochet on it. Use it when the first row of the pattern is double crochet.

Questions

What does fsc mean in crochet?
Foundation single crochet: a stitch that makes one chain and one single crochet together, so that a whole row of them takes the place of the starting chain and row 1.
Is foundation single crochet the same as a chainless foundation?
It is one kind of it. Chainless foundation is the name for any start that makes the chain and the first row together. Foundation single crochet is the one with a single crochet on each chain.
How many foundation single crochet do I make?
As many as there are stitches in the first row of the pattern. Do not go by the number of chains the pattern asks for, which is one more.
