It really depends on the pattern you use. Some require significantly more yarn than others. A simple DC stitch would use less than a SC stitch (for example).
Your answer depends on the gauge that you knit with the yarn and needles that you want to use and the size of the afghan that you want to make.Can you do the math?
The average litter size for a purebred Afghan Hound is 6 to 8 puppies.
The size of the needle depends on the gauge of the pattern you are using. If you are not using a pattern, or are using a pattern that has no gauge, then check the label of the yarn used. Most labels today will give you a size of needle that they recommend for that specific yarn.
Size...Afghan is big like a blanket and lapghan is small, meant to cover legs.
Then your shawl is about the right size.
2 to 3 becase life is hard there
A lot
Your answer depends on these variables:The measurements of the finished afghanThe gauge of the yarn given the stitch, needle size and the number of stitches per inch are produced in your sample swatchThe total yardage in each skein.
king size
An eastern king is just a standard king - i.e. not California King - 76"x80"
you don't cast on to crochet. you do a base chain. to answer this question, you need to take into account the size thread you are using and the size hook. why don't you do crochet a diagonal stitch afghan. when it gets to be 60" wide, you decrease. there is a book delma's diagonal stitch which you can get, or search for a free diagonal stitch pattern. good luck
it all depends on how big the people are. a king size bed fit 2 or 3 average people.
