One thing I learned on my first quilt (over 20 yrs. ago and still not quilted) was a sampler quilt taught in a woman's basement to all new quilters.....Make sure whatever you choose that you have "light, medium, and darks". (This quilt just "sits" there and just sits there".
Also when you're choosing, lay it out on the cutting table and "stand back", squint your eyes and you'll notice right away which fabric will POP and which will fade into the quilt.
Never fear....some day it will be easier to choose.
Good Luck!!
