Stock Solutions

Stock Solution 1

  • This is a very simple solution, so we only need a one line description of how to make it.

Stock Solution 2

This is a more involved solution, so we will describe how to make it in several steps:

  1. Step 1
  2. Step 2
  3. Step 3


  1. Step 1
  2. Step 2
  3. Step 3
