I always have success with Ottobre patterns for my son, so that's where I started. This is pattern #38 from issue 4/2011. They are called "Algebra corduroys." Ottobre pattern names are always interesting. I like the narrow legs, the curved yoke and the angled pockets on the front.
All of the topstitching is done in tan thread. I copied the rear pocket top-stitching from the pattern.
My son is the most tactile-aware of my kids. He loves soft, fuzzy clothes. He really likes these pants, even though he said he would prefer that the soft part be on the inside. :)
