When you make your little's jersey, the lettering will have a certain pattern. Family Fabric is when that same pattern is used on everyone's jersies in your family. If you pick something that will be used for years and years in your family, pick some traditional but also something that is nice. My family had what is known as "family plaid". Blah. Everyone else in my chapter was getting these jersies with bright colors and patterns; my family was stuck with this drab blue and green plaid. No one in my family wanted to keep up with the tradition since the pattern was so ugly so no one from my pledge class and thereafter used family plaid. Oh well. So, make sure the pattern you pick will be something that will still be styling years from now.
