i sew/quilt in my small dining room. because of the increasingly
large quantities of fabric being gifted by mil church group, yard sale & estate sale finds & living in small house w/o location for sewing room and attendant storage for fabric, i started using the flat underbed boxes several years ago. easier to tote downstairs for scrap projects ..or even open several on spare bed while i sort thru looking for scraps or larger pieces. i can fold fq's and large scraps and stand on end like books. easy to quickly finger thru & look for print color etc. i will put up to ~2 yrd pieces folded and stood on edge same as fq's. this method has evolved over last few years as i've adjusted to new lack of room for my sewing, quilting and yarn hobbies. but more to your query ..i've had no issues with storing in the plastic boxes. cardboard boxes smell (to me) and the acids in the paper of the boxes, glue etc will be detrimental to fabrics over time. maybe not the few weeks you plan for your project. but unless your plans fare better than mine ..a few weeks can easily stumble into a few years. like the mystery quilt from three years ago that i was determined to finish last winter ..and the winter before!
