DESIGN GENERATE – 3. Pattern Pieces
Templates are a shaped piece of rigid material used as an outline for processes such as cutting out, shaping, or drilling.
Patterns are a template used in sewing, from which the parts of a garment are traced onto fabric before being cut out and then put together; they are usually made of paper.
Jigs are a device that holds a piece of work and guides the tool operating on it.
Why would you use a template or pattern piece?
Templates and pattern pieces help you produce a precise product that will fit together if cut to the pattern. The use of them help you repeat the work precisely.
When would you use a template or pattern piece?
You use a template or pattern piece at the start of the making process, when you are marking out the material you require. You have to make sure that the pattern stays in place while you are cutting around it, if you are using a pattern piece on fabric you should either weigh it down or pin it to the fabric. If you are using a template on a piece of wood, metal or plastic then you should weigh it down and make sure it will not move.
What is a jig used for?
Let me get this straight we are not talking about any form of energetic dancing. A jig is used to repeat the same making operation over and over again, you must remember not all jigs look the same. Jigs help with a process called repeatability, this helps all products look the same and it’s makes the making easier. A couple of examples of jigs are bending, drilling and assembly jigs, they would help you do the same job over and over again.
When would you use a jig?
You only use a jig if you are going to perform the same operation multiple times and you require a precise replication of the process. If you are making a one off product, and you are only going to perform the process once you would not require the use of a purposefully made jig.
