If you mean what i think you mean then you would ch4(counts as frist dbl and ch1) and turn then skip the frist dbl cluster and start your next cluster between the next 2 clusters(in the space between the 2)
It would look something like this.
Row 2 lll lll lll lll lll l
Row 1 l lll lll lll lll l
If this doesn't make since let me know and i will try to post a photo of what i mean.After crocheting for 30 years its hard to explain in writing
