What is Mirroring in Knitting?

 In knitting it is visually appealing to mirror increases and decreases. Other elements should mirror as well.

What is a mirror image? A mirror image is a reflected duplication of an object that appears identical but is reversed perpendicular using the center as the dividing point. In essence right and left are reversed.

So to mirror decreases and increases that appear at the start and end of a row, three things must happen.
1. The slant of the decreases or increases should be in opposite directions.
2. There should be the same number of stitches between the selvedge and each decrease/increase.
3. There should be same number of stitches between each decrease/increase and the center.

Below are some charted examples of decreases: 

Above: The decreases are blended. Notice the slant in opposite directions and are equidistant from the edges.

 

 

 

 

Above: The first chart has the decreases slanting opposite, but they are not equidistant from the edges. In the second example they are equidistant from the edges but they are not slanting in opposite directions. 

What about the bar increase?  Since it has no slant, that part of the definition is taken out. The "bar" is visible, therefore to mirror the increase, there would need to be the same number of whole stitches before the first bar and after the last bar. Here is a post that explains how to do this.

To mirror within motifs, again the same idea applies. To mirror motifs, the same idea applies.  Below are some examples of how to mirror within motifs:

Above: The top motif shows decreases that are not mirrored while the lower motif shows mirrored decreases.  Here we really see the symmetry that is needed to create mirroring. 

 

 

 

And finally, above we see motifs that mirror within themselves and to each other. 

 

Mirroring is part of balance and visual harmony.

Considerations When Making Yarn Substitutions

Qualities of the Original Yarn:

--Gauge and Yarn weight
Usually, the gauge can be matched by using a yarn from the same category on the CYCA “Standard Yarn Weight System.”  Yarn weight refers to the thickness of a yarn. The CYCA yarn standards categorize yarn based on wpi or wraps per inch and ypp or yards per pound.

For worsted weight yarn(#4):  Using the yarn from the pattern, determine the number of yards per 50 grams; figure 15%.  Look at the yarn you want to substitute and figure the number of yards per 50 grams.  If this number is within 15% higher or lower than the original yarn, it is probably a good match.
For fingering ( #1), sock (#2) and  dk weight (#3) figure 20%. For bulky (#5) and super bulky (#6), figure 10%.

To determine the approximate gauge a yarn will knit when two strands are held together (doubled):  multiply the stitches per 4 inches listed on the ball band by .73 (or 73 %).  Remember you will need to double the amount of yardage that you buy.

--Fiber
Fiber content will influence how a yarn looks when knitted. Substituting a yarn with similar fiber content and structure will help obtain a fabric similar to the original. Animal, plant and synthetic fibers all have unique characteristics. All yarns will have specific qualities depending on their source.
--Ply
Compare the ply of the substitute yarn and the original yarn. Ply affects a yarn’s balance. Single ply and various multiple ply yarns will all work up differently. Even the direction of the ply (Z or S) will affect a fabric’s look.
--Texture
Determine if the item being made needs a certain texture for the yarn. Smooth yarns will highlight stitch work better.  Other textures include slubby, boucle, haloed eyelash, and thick and thin yarn.
--Drape
Fiber, ply, texture and gauge will all affect the eventual drape of the fabric. Drape is a description of the firmness of the knitted fabric. Decide on how flexible or stiff the finished fabric should be and choose a yarn with a fiber, texture and ply worked at a set gauge that creates this drape.

Other Considerations:
Use- Stranding, steeking, felting, lace, cabling.....
Color- Check that colors will work with stitch pattern and/ or written pattern. Check for bleeding.
The Recipient- Consider preferences, allergies, cost, and care.

Work a Swatch
Make a swatch that is at least four inches by four inches. Include stitch or color patterns from the pattern. While working the swatch look for any potential problems and see how the yarn feels to your hand. Check the gauge.  Block the swatch. Check the gauge again. Blocking will also give you an idea of how the yarn launders.   See the post on how to measure gauge.

Buy the Right Amount:
Using the original, yarn multiply the yards per ball by the number of balls needed for the pattern.  This gives the total yardage necessary.  Take this number and divide it by the yardage per ball of the new yarn to find the number of balls needed.  Consider getting extra yardage, you never know if you will need it.

# of yds on original ball of yarn  x  # of balls needed for size on pattern ÷ # yds on substitute ball of yarn = # of balls needed of substitute yarn.

The Bar Increase or Kfb (Knit in the front and back)

 The Bar Increase is considered decorative in some fabrics and blended in other fabrics. It is abbreviated-- kfb because you knit into the front and then the back of a stitch. This creates a small bar to the left of the stitch, which is visible in stockinette making it decorative. It is less noticeable or blended when strategically placed in ribbing, or when used in garter stitch because the bar blends in with adjacent purl stitches. Depending on where you place the increase, it can also blend in with seed stitch and other pattern stitches. Always swatch to see what the increase will look like and to find the best place to put it.

The increase is simple to work. Insert the right needle into the next stitch as if you were going to knit it. Wrap the stitch as if you are going to knit it. Pull the loop through, but do not remove the stitch from the left needle. Take the right needle and insert it into the back of the same stitch. Wrap the stitch again and pull the loop through. Remove the original stitch from the left needle.

Below the photos show the bar increase in both stockinette and ribbing.

When placing this increase on opposite selvedges, it's important to mirror the increases. Mirroring means that there will be the same number of stitches before the bar on the right side and after the bar on the left side. To do this: On the right side work the number of whole stitches desired minus 1. In the next stitch work the bar increase (kfb). Since the bar appears to the left the whole stitch will appear to the right of the bar. On the left side work to the desired number of stitches wanted after the bar plus 1. Work the bar increase. Since the bar is to the left of the stitch, the remaining stitches will need to be the desired number.

Example: You want 2 stitches at each selvedge between the edge and the bar. On the right: Knit 1, kfb into the second stitch.  On the left: Knit until 3 stitches remain, kfb into the third from the end. 2 stitchess will remain. 

There is a small hole that appears below the bar. To mitigate this, don't work too tightly. When manipulating fabric close to the edge is it also common to have tension issues or guttering, so take care to manage your selvedge tension on these rows.
