US and British Crochet Terms

 "Crochet hook size charts"

Crochet terms vary while using vintage or British patterns. They are a bit different than the US instruction terms or abbreviations.  The stitches are created the same but we must be aware of the different hook sizes and the different terms used.

Wood, bone, plastic or aluminum hooks

Also there is a bit of a difference in the crochet terms used. So to help you out I have listed differences and charts below so you can adapt. I suggest you print off this information and keep it with your knitting and crochet supplies.

What the hook or needles are made of will make no difference in the size. The material they are from will make a difference in working with the hooks or needles. I prefer metal to plastic, it just seems that the work slides better. But there is many other types of materials from which these are made.

Using Vintage or British Crochet Patterns Requires A Few Adjustments.

For successful crocheting of vintage patterns it is important to follow a few simple rules.

1. - Obtain a suitable yarn

2. - Use appropriate needles

3. - Crochet a tension square

Yarn Differences Than and Now

Yarns have changed a great deal since many of the patterns were published, especially if the instructions or crochet terms were written before 1970. Many of the older patterns recommend 2-ply and 3-ply yarns which are now difficult to find.

The old 2-ply and 3-ply were thicker than modern 2-ply and 3-ply and these patterns can often be knitted or crocheted in 4-ply

When using modern 2-ply or 3-ply yarns, use the needle size given in the patterns; Remember to check your tension first. Since modern 2-ply is finer than the old 2-ply, it may be easier to get the right tension using a 3-ply for a 2-ply.

Modern yarns are usually heavier then the original yarns and some extra yarn is usually required for the pattern.

Patterns from the 20s to the 40s yarn requirements may be increased by half as much again.

Patterns from the 50s to today the quantities stated in the patterns should be ok.

Remember 1 oz is approximately 28.35 grams

US to UK Equivalent
The chart below is to help you but is not exact. The tension square is very important in choosing needles or hooks.
