yes buy nuetrals white biege and each time you want to buy fabric use this rule
1 yd if you like it
2 yds more than like
3 yds you love it
pick fabrics that have various colors for focal fabric
stripes, plaids and so on
always start w/ a focal fabric and pick colors from there
you will soon find out you like a certain style brand or colors and your stash starts matching more and more
Do not invest alot in Fat Q's unless making scrap quilts'
Better to buy 1/3 yd because you get more in width 44 inches across rather than 22" inches
