SplinterGroup ..... but I never had the heart to cannibalize one of my "precious's" since I'm down to maybe 20 or so.....
The tie-downs are so cheap (at least here in Aussieland)... especially a bulk 4 pack, that they'd be worth the investment even if you only made boxes. 2 straps could save 8 Be$$ey$.
If your first cut is too short... Take the second cut from the longer end... LBD
