I stumbled across this pin last week, a mini weaving made using a clipboard as a loom. It's a photo from Rachel Denbow's Instagram account. If you've ever googled how to weave I'm sure you've come across one of her amazing weaving tutorials for A Beautiful Mess. Each one is fantastic and well worth checking out.
I scoured Rachel's blog but couldn't find anything showing how she did it. I did however find a tutorial Rachel wrote on A Beautiful Mess showing you how to make a woven necklace using a piece of cardboard as a loom. Even though it's not exactly the same, a shed rod isn't used to help separate the warp threads, the principles are the same and I was able to combine the two to come up with my own clipboard loom.
I've covered the basics below but if you want to see anything in more detail like how I made the tassels you can read my original Diy Woven Wall Hanging post where I used a stripped art canvas frame as a loom.
