I'm sure someon'es already thought of this but I love the idea of using natural sea or I guess sort of natural...... (...... like seaglass)...... items in the garden...... especially the coastal garden...... using premade pots or homade I suppose and adding patterns of seashells by attaching seashells or sea glass of course...... to the outside of the pot...... also adding shells and seaglass to stepping stones or making stepping stones in the shape of shell...... If shells are big enough I also like using them as planters or at least make plants...... short ones of course most likely spill out from them onto the ground....... It's nice to scatter shells through the garden...... :)
