Surface Slip Stitch Crochet.

Use a smooth, pale yarn for the background and a contrasting smooth yarn for the surface line. For this first exercise, choose yarns of similar thickness that can be cared for together. A very bulky line on a thin base makes it harder to judge whether the stitches are pulling the background.

To make the background, chain fifteen. Single crochet into the second chain from the hook and each remaining chain: fourteen stitches. For each of the next five rows, chain one, turn and single crochet into all fourteen stitches. The turning chain does not count and the first single crochet goes into the first stitch.

After six rows, fasten off and weave in the background tails. Keep the separate surface yarn unattached for now. An existing plain swatch is also suitable if it has a clear row of interior gaps and enough fabric around the planned line.

If the background count is unfamiliar, work through the single crochet lesson first. This surface exercise adds decoration, not another structural row to the edge.

Lay the background flat and choose its display face. Find nine consecutive gaps between neighbouring stitch bodies along one interior row, with at least a row of fabric above and below them. Use natural openings between stitches rather than piercing a strand.

Mark those nine points A to I along your intended direction of travel. A is the start, B the next gap, and I the finish. You can place loose contrast-thread markers beside the gaps so that the openings themselves remain accessible.

For right-handed practice, arrange A at the right end and I at the left. Reverse that arrangement for left-handed practice. The yarn still feeds behind the fabric in either case. Rotate the entire background if that makes the hook movement easier; keep the display face towards you.

You will make eight surface stitches between these nine points. The starting loop at A is just the anchor; begin counting when you stitch into B.

Make a slip knot in the contrast yarn, leaving a tail long enough to weave through the background later. Hold the knot and ball-connected working yarn behind the fabric.

With the empty hook in front, insert it through point A to the back. Place the slip-knot loop on the hook behind the fabric, then draw that loop through A to the front. Keep the small knot at the back rather than dragging it through the opening.

One loop is now on the hook in front. The free tail and the strand leading to the ball remain behind. Use your other hand to support the fabric and guide that working strand; do not bring the ball yarn over the front of the background.

This loop is the starting anchor. It is not an extra chain to count alongside the eight surface stitches.

Keep the starting loop on the hook and insert the hook through point B from front to back. Catch the working yarn behind the fabric with a yarn-over.

Bring the new loop through B to the front. If you pause here, you have two loops on the hook: the old loop from A and the new loop from B. Draw the new loop through the old one to finish the slip stitch. One active loop remains.

The first link spans A to B. Let it rest on the fabric without shortening the distance between those points. Do not tug the working yarn hard after the pull-through; that can tighten the finished link below the size it needs.

Once the movement is comfortable, drawing through the fabric and through the old loop can be one continuous motion. There is no extra chain between the marked points.

Repeat into C, D, E, F, G, H and I in order. At each point, enter from the display side, catch the yarn behind, draw a loop through the fabric and pass it through the old loop. Finish with one active loop each time.

After reaching E, lay the background down before continuing. You have made four completed links, from A to B through D to E. The unworked background on either side should still lie naturally. Check again after I, when you have eight links.

If the base bunches, undo the tight links and remake them with enough yarn to span the original gaps. Comparing a larger hook may help, but it does not replace checking the length of each surface stitch. If the line sits in loose loops above the fabric, reduce the excess gently rather than cinching the whole line at once.

Turn the piece over and check that the contrast yarn follows your line without long snags across other openings. The decoration sits on the existing six-row background; it does not add a row or change its fourteen-stitch width.

At I, cut the contrast yarn with enough tail for weaving in. Draw the cut end all the way through the active loop to fasten off, keeping the final link relaxed.

Thread that tail onto a blunt yarn needle. Take it to the back through the ending gap beside the surface yarn, without splitting either the background or the last link. Weave the start and finish tails into the back of the base, changing direction as appropriate for the yarn and leaving the front line undistorted.

This exercise is an open line. Do not take the finishing tail back to A to form a ring. A closed outline needs its own joining plan; a finishing join is not an extra decorative interval here.

Remove the temporary markers and inspect both faces again. The finishing guide explains why fastening off and weaving in are separate jobs. Snipping the yarn flush at the last visible link leaves no useful tail to secure.

For a second line, mark a gentle curve with more closely spaced points where the direction changes. Choose accessible gaps and check how the unstretched background lies before adding the yarn. Avoid stretching a single surface stitch across a wide corner just to reach the next marker.

A crochet stitch is not necessarily as tall as it is wide. A design drawn on a square grid may look different on the actual fabric, so assess letters and shapes against the real row and stitch spacing.

Use the gauge guide when size matters. Neither a neat-looking line nor the same number of surface links guarantees that two backgrounds will carry the same-sized design.
