Increasing (inc)

When a pattern calls for an increase in stitches, instructions are given to ensure that continually working in the pattern is not lost. Single increases can be worked either at the beginning or end of a row, or in the middle of a row. For a large number of increases, such as adding on the underarm stitches for a sweater, can also be made at the beginning or end of a row. When working a large number of increases a new foundation chain must be made and worked in the row to form a base for the new stitches. One chain counts for every new stitch.

Increase 1

Increasing stitches

In order to increase one stitch at the beginning of a row, make a turning chain but instead of skipping the first stitch, work the first stitch in the top of the last stitch of the previous row.

Increase 2

Increasing stitches

For increasing one stitch at the end of a row, work in the pattern to the last 2 stitches, work twice in the next stitch, then work the last stitch as usual in the top of the turning chain.

Increase 3

Increasing stitches

To increase several stitches the the beginning of a row, work a foundation chain, or a chain for every new stitch required plus one chain less than the turning chain. Skip the necessary chain, then work a new stitch in each chain.

Increase 4

Increasing stitches

For increasing in the middle of a row, work twice in one stitch. Complex patterns should give precise directions to ensure that increases follow the previous pattern lines.

Decreasing (dec)

When decreasing, two stitches are worked together. This can be done either in the middle of a row or on the side edges. To maintain a neat edge, decreases should be worked before, but close to, the edge stitches.

Decreases are easy to work, especially on basic stitches such as single and double crochet.

To decrease several stitches at the beginning of a row, make the required number of slip stitches, then work in the next stitch. Make a turning chain and continue the row as instructed.


To work in the “short row” method at the end of a row, work the pattern until the required number of stitches remain, then turn for the next row, leaving the final stitches unworked. Or you can skip a stitch at the beginning or end of a row.

Though working is decreases is simple, it can sometimes be difficult for a beginner to keep an accurate check of how many stitches have been lost or added, and at what point in the pattern. It’s a good idea to occasionally stop and count the number of stitches that you have increased or decreased to ensure you’ve done the right number. The edge of the work should be straight.

Marking a stitch or row

Tie a piece of contrasting yarn around the first increased or decreased stitch. You can also use a safety pin to mark your place. After that, subsequent increases or decreases are then easy to work in the correct sequence.

Decreasing stitches

To decrease one single crochet stitch by working two stitches together, insert the hook in the next stitch, draw a loop through, insert the hook in the next stitch, draw the loop through. There will be three loops on the hook.

Pull the yarn over the hook, and draw through all three loops on the hook. One single crochet stitch has now been decreased.
