Each punch needle has a different thickness. To ensure that your loops stay nicely in your fabric, it is important to use the correct fabric for your project. If a fabric is too open woven it might be nice for the thickest refill needle of clover, but when you work with a finer needle your loops will pull out easily. And if your fabric is too dense it will be harder to punch with the thickest refill needle.
We tested the clover punch needle with a large number of fabrics to provide you the best fabric that works with all 4 different refill needle sizes of the clover punch needle.
