Looks like a sketch most could do in 5 min. When it took me 40 
. But this was inspired by my own experiences of having to carry a backpack weighing anywhere from 5-30lbs of books, etc approximately 15-30 minutes walking distance (in middle school, this was). Straps are of a thicker, stronger material than usual (to avoid broken straps). It has an extendable pouch for more books and supplies (should the teachers be so cruel). And padding on the shoulder sections of the straps, to bear all that weight. Sorry it’s not colored. I suppose it just comes in whatever color you want. (1st post, btw)
