I think that sometimes people make scrappy like you do using all scraps and then there are those who make "controlled scrappy" for those who do it like the people in your group. It's all a matter of what makes you happy as well as less intimidated some people just can't do it, it stresses them out and they feel like they have no control or it just won't look right. Obviously for alot of us that is not the case. :-D
