When it comes to sewing with hemp fabric, choosing the right needle is crucial for a successful project. There are a few key factors to consider while picking the needle that will yield the best results.

Considering the Fabric Weight

One of the important considerations when choosing a needle for hemp fabric is the weight of the fabric. Hemp fabric can range from lightweight to heavy, so selecting a needle that matches the fabric’s weight is essential. For lightweight hemp fabric, a size 70/10 or 80/12 needle will work well, while heavier fabrics may require a size 90/14 or even a 100/16 needle. By using the appropriate needle size, you can ensure that it glides through the fabric smoothly without causing any damage.

Using Sharp Needles

Another crucial aspect of selecting the right needle for sewing with hemp fabric is to use sharp needles. Hemp fabric, although durable, can be dense, and using a dull needle can lead to skipped stitches, snagging, or even fabric damage. Opting for sharp needles, such as Microtex or Universal needles, will ensure smooth penetration through the fabric, resulting in clean and precise stitches.

Opting for Ballpoint Needles

If you are working with hemp knit fabric, it is advisable to use a ballpoint needle. Ballpoint needles have rounded tips that slide between the knit loops instead of piercing them, preventing snags or runs in the fabric. This type of needle is ideal for jersey or interlock hemp knits, as it allows for easy and seamless stitching without compromising the fabric’s stretch and structure.

Selecting the Proper Thread

Choosing the right thread is just as important as selecting the correct needle when sewing with hemp fabric. The thread you choose should complement the fabric and provide the necessary strength and durability for your project.
