Don't you hate when your 1/4" leather lace does not fit thru your 1/4" holes?  I found that to be the case most of the time.. so our "chubby" laces are durable, yet thin enough to fit thru 1/4" holes.. allowing your parts to wiggle!  Bird-safe vegetable tanned leather is soft and easy to knot.  Sold in 36" laces.. a convenient size for toymaking!
