My daughter has become adept at taking interesting photos as inspiration for her quilting and fabric art.  Often these will be bits of bark, barn siding, flower segments, and other textural objects.
Then she incorporates them into many of her small quilts, utilizing a variety of techniques.
This photo of barn siding offers suggestions for textural ideas you may want to try.
Sometimes you might get ideas from a single photo.  Other times you can try combining a variety of close-ups.  Or you can vary the close photos with distant scenery to give you a fascinating combination.
