Here at Calico Laine we stock a huge amount of fasteners for dressmaking but by far the best selling fastener is zips and you can Buy Zips from our large selection online or in store. With a huge range of zips to choose from we will always be able to offer you a solution for your dressmaking queries. One of the most important things you need to know when you Buy Zips is the size that you require. Zips are measured from the top of the teeth to the bottom of the teeth rather than from the top of the fabric tape. The majority of our zips are available in even numbers for example 24", 26", 28" so it is always best to pick something that is closest to an even number when you are buying replacement zips. If you cannot find a zip that is the correct size, we would usually suggest to Buy Zips that are larger as these can be cut down to size or sewn in a facing to create the correct size. Another important thing to know when you Buy Zips is whether you need an open end or closed end zip. Open ended zips open fully at the bottom and both sides will fully separate from each other for example, a jacket zip where both sides come apart at the bottom. Open end zips that are stocked at Calico Laine include metal open ended, plastic open ended and nylon open ended. If you do not require this type of zip, you will usually require a closed end zip. These zips do not open fully at the bottom and are usually used for dresses and trousers where the garment does not need to separate. If you are unsure about what type of zip you need when you are looking to Buy Zips, please feel free to contact our sales team and we can always advise you on what will be the best for your project.
