LEARN TO CROCHET
The Basics
Texture plays an important part in the beauty
of crochet. The finer mercerised threads (#100, #80 or #60) are
more effective for delicate designs used for tablecloths, doilies
and edges. However for some of us, if seeing and grasping the
thread is a little challenging, work in a larger thread such as
#10 or 4ply cotton. The crocheted items will be larger so this
will have to be taken into account. Also consider that different
brands or colours of the same size thread may vary in thickness.
Avoid joining the thread in the middle of a
pattern and never make knots to join the thread. As the thread is
coming to an end, place the new thread along the top of the work
and crochet a few stitches over this. Before the old thread has
run out, change to the new thread and work the stitches over the
old thread. Cut off or weave in any ends that are left.
Embroidery Threads Cotton perle (pearl) embroidery
threads, although generally softer and more shiny than crochet cotton, may be
used in crochet patterns as follows:- #5 perle is a little thicker than #10
crochet cotton but is suitable for most #10 cotton patterns; #8 perle is about
the same as #20 crochet cotton and #12 perle is about the same as #40 crochet
cotton.
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.

When using an American pattern that requires worsted weight yarn
and you want to use 8ply yarn and a 4.00mm hook, remember the article will
probably turn out smaller, so from the tension, add more stitches / rows to
achieve the required size.

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.

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.

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.

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.
