Yes, yes, and yes! Hobby Lobby, Michaels, JoAnn Fabrics have all kinds of stuff that us fly tyiers can use such as feathers, beads, stretch cord, small diameter vinyl tubing, yarns, furs, craft furs, etc. etc. This is not a diss on LRO or any other fly shop. Lord knows I spend a ton of money at my local fly shops, so I feel that I am supporting them.
But the craft stores do have some items that can be attached to fly hooks. Just roam the aisles and let your imagination run freely.
