I'm just graduating beyond tea towels now that I have a year of practice and am ready to try the Hannah blanket (kit) from Glimakra. I'm ready to thread, but there are two empty columns between the threading and the tie ups. The empty columns are on the threading side, separating threading from tie ups. I know in Handwoven Magazine they use "bullets" to denote floating selvedges. This is a kit with Swedish tuna yarn. Is there a different custom there? There are absolutely no remarks about these empty column in the direction pages. Thanks for any light you can shine on this! Sue
