Wendy-Marie was really interested in trying the scarf that appeared on the cover of Handwoven May/June 2017. She tried a new colorway and wove her first scarf. Immediately she didn't like what the spacing of the yarns in the reed did to the plain weave portion of the scarf. Since the technique to make the medallions at each end of the scarf requires that you skip three dents between the motifs, the plain weave sags into these open dents. See the photo below.
In trying to figure out a system to get around this problem, Igor and Beryl suggested she borrow their Open Reed This would allow her to sley the reed according to the directions given , but when the plain weave portion of the scarf began, she could open the top of the reed, and move threads over for even denting, recap the reed and start weaving. When she reached the border motifs she again opened the cap on the reed and reversed the process to leave the open dents.
Here is the reed with the open dents
And here is the reed with the warp resleyed
Because moving threads with the open reed can be tricky, it was suggested that she brace the reed so that it wouldn't fall forward or backward during the resleying process. Meticulous work, but it paid off. Below is a close up of the finished scarf. Notice the nice clean appearing plain weave section.
And here are the two scarfs shown side by side. The results are more pronounced when you can see the scarves in person, but the Not 2 Square weavers did like the "fix" for this design.
