In Chapter 22 I gave you everything you needed to know about modeling a scrap tie pile.
In this chapter I'll tie (pun unintended) the two ideas together in modeling a load for a gondola. I again used my wife's (used) Diamond matches. They come 300 to a box so you get plenty to go the distance should you choose to make a full load (photo 1). I made a partial load filling in the remainder of the floor with bric-a-brac and some Monster Model Works tie plates. The ties only consist of a single layer on top of a piece of 1/8 tick balsa and some grey cardboard for height (photo 2). I painted/stained the match stick ties individually with a combination of black, grey and brown. This is a bit tedious but, (I think) worth the effort for achieving realism.
A caveat: I don't go to the rather insane level of explanation the contemporary modeling magazines go in describing my how-to methods. The "chapters" are meant to be inspirational. If you chose to follow up on any of my ideas you welcome to approach them in your own manner.
