Can I put one more suggestion on the table?
On the assumption that you intend to buy at leat 50 fat quarters, have you considered colours yet? There will be a whole rainbow of colours to choose from.
My suggestion is that you consider choosing perhaps 5 or 6 basic colours for your pallete, and then choosing 10 fat quarters to closely match each colour. This would keep your selections manageable. Many quilters like to use a variety of closely-matching fabrics as a single colour (called going scrappy).
Also consider that you will probably need at least one colour which is lighter than the rest, and one which is darker. This is termed 'value', and most patterns rely on contrasting values to highlight the pattern.
Google 'colour wheel' when you get a chance, as this can help you choose your basic colour palette.
Another trick - when you get your selections gathered together, stand back from them slightly, and look at them with your eyes half-closed (kinda squinting at them lol). When you do this you often can see if something in the collection stands out as not matching, and you can remove any that don't seem to work before purchase.
Good luck with your retail therapy lol
