HINTS:
To keep your yarn from twisting, change the way you turn your work after you've completed each row - for example, turn your work clockwise after each even numbered row and turn it counterclockwise after each odd numbered row.
Use a tapestry needle (it has a blunt or non-sharp end) to weave the ends of your yarn into your work when you are finished. A size #16 Tapestry needle, commonly used for Plastic Canvas stitching is a good size to use for worsted weight yarn crochet patterns. When weaving in your loose ends, weave them about 2 inches in one direction and then back 2 inches in the other direction.
GUIDE TO DIFFERENT SIZE YARNS:
"Worsted Weight" or "4-Ply" yarn is the most common yarn used for projects. It has 4 individual plies of yarn that are twisted together. Some of these worsted weight yarns may be slightly thicker than others, which is why it is important to check the gauge for each pattern.
You will usually use a hook size of G, H, or I for this yarn.
"Chunky" yarns are thicker than the worsted weight yarns. They are often special yarns such as "Angora", "Mohair", "Chenille", or special crimped yarns such as resemble bathrobe cotton.
You will usually need a larger hook to stitch these projects such as J, K, L or N.
"Sports Weight" or "3-Ply" yarns are thinner than the worsted weight yarns by one ply; they have 3 plies of yarn twisted together. This yarn is often used in project for babies - booties, outfits, etc. - to give you a stitch pattern that is smaller and more proportioned to a small outfit. These yarns frequently have a metallic looking thread running through them to add sparkle.
You normally use smaller hooks such as F, G and H for these yarns.
"Baby Weight" yarns are usually even thinner than "sports weight" yarns but they usually have 3-plies as well. Make sure if your pattern calls for "Baby" yarn, that you compare that brand of yarn to a "Sports" yarn to see if they are the same before you substitute a "sports" for a "baby" yarn. Once again, it's extra important to check the gauge on this yarn to be sure your pattern will turn out correctly sized.
This yarn also uses the smaller hooks sizes - F and G.
"Crochet Cotton" comes in different thickness described by numbers: #10 is a popular size. These cotton threads are used for very fine projects such as doilies or lace.
You would use a completely different set of hooks for these projects: they are usually silver only - called "steel" (rather than "aluminum") and are in sizes A, B, C and in numbers such as 1, 2, 3.
Other types of materials you can crochet with are strips of material (actual fabric cut into thin strips and tied together) or even strips of plastic such as from plastic garbage bags. You would use the large size hooks such as N, P and Q for these materials. Also, you can use these larger hooks when holding 2 or more strands of worsted weight yarn together at the same time (using 2 different colors of yarn makes a nice variegated effect).
