Context: I just purchased the most expensive sweater of my life ... and I have to make it . I am beginning my first endeavor into the ancient art ( I do n't really know how ancient it is ) of sweater making . I typically stayed with hats , scarves and the occasional mitten because those things are easy to make and they 're quick ( one or two movies and a brand new wearable piece of art ! ) . But a sweater ... that takes commitment .
Question: What may be the reason for their interest in sweater making ?
Options: 
- They want to challenge their skills .
 - They want to sell sweaters .
 - They want to gift others with sweaters .
 - None of the above choices .


They want to challenge their skills .
