LEARN TO CROCHET

AMERICAN THREAD / YARNS

American threads usually use the same sizing as our own for crochet cotton sizes such as our number 10, 20, 40, etc. shown as No 10 or #10 etc. Bedspread weight yarn generally refers to our No 10 crochet cotton but some patterns may use thicker yarn such as No 5 or even our 4 ply cotton, so check hook and tension specified.

Yarn sizes however are generally provided as a weight of yarn such as worsted weight, sports weight, etc. The following provides a very basic guide for determining the yarn to use and should be used in conjunction with any specified hook size and tension.

CROCHET HOOKS

Crochet hooks are made of steel, plastic and alloy metals. Each hook is used with a set size of thread unless otherwise stated in the pattern. A pattern should specify a hook size and a tension, so a larger or smaller hook may be required to achieve that tension. If the crocheting is too loose, use a smaller hook, if the crocheting is too tight, use a larger hook. The table below is to be used as a guide only for thread and hook size.

SIZE and TEXTURE

The picture below provides an indication of the change in size of an article when crocheted using the same pattern, but using different thread sizes (with the appropriate size hook as above). Using a finer thread results in a smaller but more finely textured article. Depending on the pattern, some articles may be crocheted in a wide variety of sizes while others go out of shape or do not sit flat if a different size thread is used.

The chart below provides an approximation only of how to determine the finished size of an article crocheted in a thread size other than that specified. Please note that this only works for some patterns and is a rough guide only.

Using the column with the specified thread size, go down until you locate the red 1, then go across to the column with the thread size you wish to use. Multiply the figure shown by the specified size of the article to provide the new finished size.

Example: Assume a doily was crocheted using #60 thread with a finished size of 20cm in diameter and you wished to use #20 thread. Go to the #60 column and run down to the red 1. Now go across to the #20 column and the figure is 1.4. Multiply the original size of 20cm by 1.4 and the finished size should be about 28cm.

CROCHET HOOK CONVERSION CHART - UK Imperial to Metric

The following chart may be useful when using older crochet patterns that specify the old UK imperial size crochet hooks.

CROCHET HOOK CONVERSION CHART - Metric to American

American crochet patterns also specify the use of crochet hooks that may be unfamiliar. The following chart provides approximate equivalent crochet hook sizes for our metric sizes to American sizes. The American sizes appear to vary between brands, especially from 7mm and larger. Many American crochet books now provide a similar conversion guide for hook sizes. Use the tension information, if provided in the pattern, to ensure correct hook selection.

CROCHET STITCH CONVERSION CHART - American to English

The availability of American crochet patterns provides you with the opportunity to explore your craft by using a greater variety of patterns and techniques than are generally provided by English terminology patterns. While at first American crochet patterns may appear to be written in a foreign language, American crochet is identical to our own Australian/English crochet with the exception of the names of the stitches involved. The following chart provides the equivalent stitch names for American and English crochet stitches.

WEIGHTS and MEASUREMENTS CONVERSION CHARTS
Imperial Standard to Metric

The following charts may be useful when using older crochet patterns that specify weights and linear measurements in the old Imperial system. Only the figures in red are more precise.
