Take the rectangle in the picture above as an example. The drawn line has a width, so you should follow it when cutting. Cutting on the inside of the line is the last thing to be precise. Remember not to cut while riding the line! If the pattern has rounded corners and you cannot cut the perfect rounded corners with a knife, you can use sandpaper to polish the desired shape. 3. CAD drawing The most accurate way to make patterns is CAD or AI drawing. The poster usually uses CAD drawing. Just print it out and stick it on the cardboard and cut it out. The biggest advantage of CAD drawing is that the hole spacing can be accurately displayed on the drawing. , the position of the cut hole can be measured on the drawing. If it is a hand-drawn version, it will be very time-consuming and may not be completely accurate.

After the cardboard trial pattern is successful, you may need to use a material with a certain thickness such as microfiber material or two-layer vegetable tanning to make a trial. Only after complete success can you open the leather. For formal production, don’t underestimate the time wasted in the trial version. Rather than finishing the package and not being able to use it, it is better to spend some time on the trial version.

Paper Jam Trial Version 5. Notes I have shared several commonly used pattern making methods. Finally, the author will share some pattern making with you. Experience. Pattern is not required for all parts. It may be difficult to understand. If the main structure of a bag does not have sides and lining, but only one layer of leather, such as envelope bags and card holders, then pattern making is very simple. , it can be made by drawing accurately. This pattern making method is mostly used for vegetable tanned leather. But if a bag has parts that need to be bent, including a top and a bottom, then the pattern we make only needs to be accurate for the top and the inner The skin does not need to be precise, and in most cases, the lining is pre-larged.

As long as there are two sides, it is easy to see that the length of the outer skin is greater than the length of the inner skin. , this is an issue that needs to be paid attention to when making patterns. If the inner and outer skins of a short clip are the same length, there will be no space for money after it is made.
