Let's talk weft tension in tapestry!
Maintaining consistent weft tension with the use of bubbling, as illustrated in the image above, is one of the most important aspects of tapestry weaving, lest your warps become too close together or too far apart. One of the most common issues for a beginner tapestry weaver is encountering these issues, and the scariest scenario is when your warps get so close together that you can no longer create weft-faced cloth while weaving. This means your warps are showing through your weft! The technical name for these bits of warp showing through is ‘lice’. But, if I’m honest I rarely use that term because it grosses me out. Warps getting too close together is often also accompanied by your weaving surface no longer being a straight line. The area where your warps are too close together will appear as a little hill. When the issue gets this bad it can be difficult to remedy, but don’t give up just yet!
