One of the other prerequisites for embroidering a large tapestry is that you also need a large embroidery frame. We liked to make an embroidery frame based on historic evidence (read images) and have used the fresco Triumph of Minerva as a basis. Bram and I have made two frames from beech, because this wood does not splinter. They are wide enough to rest on two trestles, while Anne or Katinka sit between the trestles working on it. While the final trestles are not yet ready, the frames are (and are in use). We have made the frame flexible in size: the long rails can move through mortises in the short rails and fixed with pins at any size. At each end of the long rails are blocks (also with mortise and pin) holding a roller where the excess linen of the (embroidered) tapestry can be wound. The long rails measure 88 x 3.5 x 1 cm; the short rails are 70 x 3.5 x 3.5 cm. The current workspace of the frame, measured from the rows of holes is 68 x 58 cm. The holes (for tensioning the canvas) have a diameter of 2.5 mm and are 1 cm apart from each other. The complete frame was waxed afterwards.

With the frame ready, the linen had to be tensioned on the frame. As our tapestry is longer than our frame, the method of tensioning is slightly different from what is shown in medieval images (which show smaller embroidery pieces). We had to fix the linen to the short rails, while the remaining linen was wound on the side rollers. To protect the canvas against to much force of the tensioning threads we used a thicker thread (see photo). The long rail could be tensioned as normal.

For ease of use, we have rewound the woollen hanks onto spools. During medieval times child labour was common. Thus, our (and visiting) children were employed to wind the spools.
