Once the gun arrived I practiced using it on Monks cloth to make my first carpet. I am a beginner to this craft and it was difficult at first getting the yarn to stay on the cloth. An hour later of failure, I was finally able to get the hang of using the gun and the yarn was threading perfectly onto the cloth. The gun works fine, I did read about maintenance on the gun and buying sewing machine oil after each project to keep the gun working properly (: I was skeptical at first buying the gun at a lower price than usual and faster shipping but the gun is good quality and works perfectly! I'm glad I bought it from here
