Depending on how you see it, knitting and crochet are both good ways to spend extra time. It can be a hobby, or something to do to de-stress. It can also be a source of extra income, if you're fond of selling your works to friends or on eBay. And come Christmas, birthdays, or any other holiday, knit or crocheted stuff are good gift ideas (the recipient will know that you've exerted effort in the threadwork).
At some point, you might be switching across these types of needlework. Knitting and crochet aren't exactly similar, although you can use patterns interchangeably with some modification. You will need some basic math, particularly fractions, in order to work this out. You will also need to be well-versed with the various stitches for each type of needlework.
When converting a knitting pattern to a crochet pattern, the most important thing to remember is gauge.
What you will need:
- Knitting pattern
- Crochet pattern
- Calculator (optional) or pen and paper.
A crochet stitch is usually twice taller than a knitting stitch. Therefore, a good rule of thumb is that one row of crochet stitches is equal to two rows of knitwork.
- Based on the knit gauge identified on the knitting pattern, you will need to convert this into inches. For example, if your knitting gauge is 4 stitches & 6 rows is equal to one inch, you will have to work out the size of the entire material (sweater, blanket or whatever final product).
- Try out different yarns, stitch types and hooks in order to arrive at the same effect in your final product. You might want to consider whether you want a solid needlework or a lighter one.
- Draw a rough sketch of the garment or final product you want to crochet. Use the measurements based on the knit gauge in step 1.
- Determine the stitch pattern you intend to use. Then, measure the gauge in terms of crochet stitches, converting from the original knit gauge. For example, if your original knit gauge is 4 stitches and 6 rows = 1", then work out a crochet stitch pattern with 4 stitches to 1".
- Compute your gauge in terms of crochet gauge. You will need to work on fractions here. For example, with our rule of thumb that one row of crochet stitch is equal to two rows of knit work, then your gauge should be 4 stitches and 3 rows = 1".
Make sure you measure your work at regular and frequent intervals, to ensure that the form and measurements of your item are correct. You will need to note that you might need more yarn when crocheting than knitting. Approximately 33% more thread will be used in your crochet pattern than your knitting pattern.
Lastly, you should expect that the garment or item you will produce through crochet will not be exactly the same as if it were knit, because of the differences in stitches and the patterns. It will be a close approximation, though.
