After examining pieces 2-5, I planned the next series of pieces, retied the warp ends to the apron rod, wove the header rows and began weaving the 6th piece on this warp.
This series will all have the same weft treadling – Unit substitution. Each piece will be woven in stripes of a single colour family – all the blues, all the reds, all the oranges and all the greens.
All the blues (denim blue, dazzling blue, scuba blue) 
All the reds (chilli pepper, honeysuckle, radiant orchid) 
All the oranges (freesia, celosia orange, friar brown) 
All the greens (cedar green, green glow)
