What is meant by Yarn Weight Classification?

The “yarn weight classification” does not refer to how much a yarn “weighs” but is a standard designation for the size (diameter) of the yarn. The “yarn weight” required for a project and the amount of yarn needed to complete a project is specified in the project instructions. “Yarn weight classification” is a number and/or name assigned to yarn in the following designations:

  1. Super Fine
  2. Fine
  3. Light
  4. Medium
  5. Bulky
  6. Super Bulky

Can I substitute one yarn weight for another yarn weight?

No, each project is designed to be made with a specific weight of yarn. Changing the yarn weight will change the size and appearance of the finished project as well as change the amount of yarn required.

Can I substitute different yarn brands of the same yarn weight?

Yes, but be sure to test the “gauge” to make sure that an adjustment is not necessary as you substitute one yarn for another. See question # 7 to learn more about “gauge.”

Why do some yarns have a dye lot number and others are no dye lot?

Some yarns are dyed after spinning. They are dyed in large batches with each batch assigned a dye lot number. It is important to use balls from the same dye batch to avoid the disappointment of minor color variances in your finished project. “No Dye Lot” yarns are spun from fiber that is already colored. These yarns are purchased in very large quantities and spun into different weights. There is a production date on these balls of yarn, and it is best to purchase enough yarn for your project with the same date on them.

What does "double knitting" mean?

Double Knitting is actually a weight of yarn like worsted, fingering or sport. It knits at a gauge of 5.5 stitches to the inch. It does not mean that you are required to knit with two strands doubled together at the same time.

Can I re-use yarn that I have ripped out of a project?

You may re-use yarn that you rip out of a project but try to get the "kinks" or wrinkles out of it first. Steaming with an iron or blocking will work: wrap the yarn around a large, flat piece of cardboard and then apply steam or lay a very damp towel over board and let dry. Never apply an iron directly to the yarn.

What is the best way to launder projects made from yarn?

The first step is to check the laundering instructions on the yarn label. This will tell you whether to machine wash and dry or hand launder and dry flat. Even if the yarn label indicates that you may machine wash and dry, remember that you are caring for a handmade item. It is recommended that delicate items be washed in a mesh laundry bag or pillow case and that you wash your handmade items separately from your other laundry.

What is Gauge and how is it determined?

Gauge is the number of stitches and rows in every inch of knitting and the number of stitches and rows (or rounds) in every inch of crochet. The required gauge is specified in knitting and crochet patterns, and determines the finished size of the project. Since everyone knits and crochets differently, it is very important that you make a gauge swatch and match it with the gauge specified in the project pattern. You may find that if you knit or crochet loosely, you may have to use a needle or hook smaller than the pattern specifies. Likewise, if you knit or crochet tightly, you may need to use a needle or hook larger than the pattern specifies. It doesn’t matter what size needle or hook you use as long as your gauge swatch has the same number of stitches and rows per inch as specified in the pattern.


Is it okay to add a new ball of yarn in the middle of a row?

The problem with joining ends of yarn in the middle of a row is that you risk having your knot come undone or popping out the front of your garment. For the amount of yarn that you save, it is not worth it. It is best to add new balls of yarn at the edges of your work.

Should I decrease and increase at the beginning and end of the row?

When increasing or decreasing, make sure you do so between the first and last stitches on a row or according to the pattern instructions.

How do you block a garment?

Pin garment pieces to measurements and cover with damp cloth leaving cloth to dry.


Important to know before felting:

  • It is important to record all the measurements and changes before and after felting. You will be able to either adjust or repeat the method to produce reliable and consistent results.
  • Always test a sample. Different colored yarns may felt differently. Some colors have to undergo the felting more than once in order to achieve the desired result.
  • As yarn will be going into very hot water, colorfastness can be affected. Again, testing a sample will give you an indication of how the color will be affected in very hot water.
  • Any knitting that has been properly felted will have a distinct texture. The knitted or crocheted piece becomes very dense and matted. This will be one of the key criteria for determining that felting has occurred.


  • Put pieces in top-loading washing machine. Using low water level, run a Hot/Cold cycle for 15 min. Put in a pair of jeans or large towel (in non-interfering color) for extra agitation.
  • Add 2 tablespoons of baking soda for a small load. After one cycle, check for size. Repeat as necessary.
  • Run through the rinse and dry spin cycle.
  • Lay felted piece onto a dry towel, away from direct heat or sunlight.
  • Shape piece to correct measurements.
  • Allow to dry thoroughly. Do not use a clothes dryer.
  • If an edge ripples, baste a thread through the edge and gather in. Remove the thread after the felting is dry.


You have spent a lot of time and care completing these items through their knitting/crocheting and felting stages. A little thought to its aftercare will ensure that you will have these beautiful felted items for many years to come.

  • After you have subjected your item to the felting process, you may think that it has gone through the most vigorous and tortured wash that yarn could ever endure. Now you assume that you can throw that felted item into the hot wash cycle along with your sheets. Do not do it! Treat your newly felted item with caution and care in order to avoid further distortion or shrinkage.
  • Felted handmade items can always be improved with brushing.
  • Even a slight pressing will give a smoother appearance to felted fabric. Always press lightly using a steam iron and a damp cloth. Never press down on the fabric but hold the iron just above the fabric.

Based on our calculations:

Knit Swatch
After felting, the sample is approx 85% of the width and 75% of the length of the knitted sample before felting.
Crochet Swatch
After felting, the sample is approx 80% of the width and 95% of the length of the crocheted sample before felting.

How do you set the dye in a yarn or garment?

Knit your project, and soak it in a solution of the following: 1-2 c PICKLING SALT and COLD WATER. Set for half an hour. Rinse THOROUGHLY in water. Soak again in VINEGAR and WATER. Set for half an hour. Rinse THOROUGHLY.


What are the differences in steel, aluminum, and plastic crochet hooks or knitting needles?

Crochet hooks and knitting needles are made in a variety of materials such as wood, plastic, aluminum, bamboo, and steel. They come in many sizes designed to be used with different yarn weights. The choice of material is one of personal preference. Hook and needle sizes are indicated by letters, numbers, or millimeters (mm). The project instructions will specify the crochet hook or knitting needle size required for the pattern.

What are double point and circular knitting needles used for?

Double point and circular needles are different from straight knitting needles and are used for seamless knitting or “knitting-in-the-round.” Double point knitting needles come in sets of four or five and are used to make smaller round pieces such as cuffs, socks and mittens. Circular knitting needles come in various lengths and sizes, and are the tools of choice for larger round sections such as sleeves, collars, and the body of a sweater.

Should I use circular needles instead of straight needles?

It is really up to you. Circular needles are more versatile as you can use them to knit “in the round” or “back and forth” like straight needles. They are good for knitting in close quarters like a car or public transport. Many people claim that they are also more comfortable to use.
