The answer in this case is no, it is common with the nature of the Unspun wool. Pilling can be caused by friction and hard use, As we advise all knits are for decorative use.

Prior to making the wool is lightly hand felted to bind the fibres together to make the wool stronger,

If small pulls/ loose fibres do occur you can simply pull them away, or take a pair of sharp scissors and snip the end away. A light steam with the iron can help to set the wool once, this is done when your item has been made, as a the final finishing process of making your chunky knit.
