There are a number of symbols and standard terms that appear on printed patterns that it is very useful to know. Without an understanding of these terms and symbols, using a commercial pattern is much more difficult. There is usually a brief explanation of these on the pattern notes, but it is worth looking at them before starting to look at patterns to buy.
Some marks should be transferred to the fabric before removing the pattern. These will be mentioned as we look at each one in turn.
Cutting Line: A solid line round the outside of the pattern. Cut the pattern out on this line first, and then follow it to cut out the fabric.
Sewing line: This is usually 5/8" inside the cutting line, but some patterns come with narrower allowances, and so do some parts of patterns! Modern multi sized patterns do not usually have the seam line marked. Read the notes carefully to see how much seam allowance is included on the pattern.
Remember, it is the seam line that has to be matched with the seam line on the other piece of fabric, NOT the cut edges!
Arrows: These are used for several things, like telling you the direction in which to make a pleat, tuck or fold, and for the grain line (see below). Read any instructions with or on the pattern to see which type you have.
Bust point/Hip point: These help you to determine the fit of the pattern. They mark where the bust or hip point of the pattern is. They help to indicate alterations when they do not match your personal bust and hip points.
Cut on Fold Line: This symbol points to the fold in a piece of fabric, and means that that edge of the pattern needs to be placed on the fold. The fold may not always be down the length of the fabric, so look carefully at the layout diagrams first! Also, they may not mean you to fold the fabric down the centre. Again, look at the diagram to see where the fold should be.
