Mine just grew up all by itself. It happened over lots of years and projects. It was certainly not intentional- In other words I did not say I am going to buy this piece so I can add it to my stash. I rarely buy fabric at full price. I want only first quality fabric and wait for sales. I like estate sales for the best fabric as the least prices. One day I happened onto one that was selling lots of attractive fabric for 50 cents a yard. I bought all they had for about $75. I have very little of it left. I also trade with friends fairly often. From time to time I purge my collection and give things to my guild or a charity effort I admire.
