before you begin a project
#crochet-beginners #status_wip
read your pattern
Always read through the entire pattern before you begin. This does not mean reading every individual crochet step. Rather, read through all the introductory information as well as any notes about starting/finishing each piece or panel.
For example, a step may say that you should leave a long tail for sewing; that's useful to know if you're someone who cuts the yarn right away after fastening off. A step may call for you to make multiples of a piece, do a color change, or mark certain stitches for later use. Some garment or amigurumi pattern call for complicated construction schematics.
You want to know these details head of time, so that you're not surprised by them halfway through your work. If it helps, highlight these notes so you quickly refer to them later.
See quick tips for my advice on leaving a tail for sewing.
prepare your yarn
Find knots in your skeins early to cut them out
Making a center pull will make it easier on your hands while you work
More consistent tension
make a gauge swatch
Very important if making something that needs to be particular size
Test drape and tension
For wool or cotton, wash the swatch to test shrinkage
Make sure you have enough yarn for the project
