You do not need a frame for stitching your tapestry however I find it a far more comfortable way to stitch. Therefore we carry stock of our preferred size of Elbesee Easy Clip frames which can make stitching the Just So kits more comfortable, but also could be used for large pieces of embroidery or applique.
We also stock an 18" by 9" size frame which is the best size for our cushion and stocking kits.
