If your sheet fabric is new, always wash it first (and tumble try if you think it will be tumble dried later on) to pre-shrink the fabric. I have used a mix of new sheets, second-hand sheets and cheap fabric to make mine. I have made a drawing below that shows how to cut the fabric (red) around the squab (white). Put down the fabric, and put the squab on top with the top side facing the sheet. If your sheet fabric has a right and wrong side, place the right side facing down (the side you'll sleep on). Basically you just extend the lines from the sides and cut out the corners, the picture below does a much better job of explaining that than I do!
How much to cut away? It depends on the thickness of your squab and how much fabric you have, but you want at least the thickness of you squabs and ideally some more. Roughly 30 cm, try and make it even all around the squab, especially the corners.
Most squabs most aren't symmetrical, for example if one end is wider than the other. One symmetric example is our v-berth. If the squab you're doing is not symmetrical, then you need to pin the corners so you know which side is. If you don't know what I'm talking about, just pin it anyway, better safe than sorry. Basically try to imagine which side of the sheet is right and wrong (or inside and outside) and then you pin the wrong side (where the seams are). Again, the photo below explain much better than I do. For your information, our squab covers are red with a (cheaper) grey backing. You only need to pin one corner to show you which side of the sheet to do the sewing on.
pinning the corners together so you know which side is right and wrong. It's enough to do this on just one corner of your sheet |
- zig zag: most fabrics unravel, so first you need to zig zag all your edges. Zoom zoom is the sound of your machine sewing all these straight edges.
- sew corners: next you sew the corners together, those cut-outs you did when it was laying flat, also see photo above.
- fold: then you make a fold where the elastic is going to be (and therefore the width of the safety pin you'll use to insert said elastic)m, approx 2.5 cm. If you're the super pedantic type who cares about how the back side of your sheets look, then make two folds, but it's harder and you need a bit more fabric. Obviously I don't care. Remember to leave a small hole where you're going to insert the elastic. A good trick is to start by a corner and fold all the corner seams the same way, which will then be the way you insert the elastic, the safety pin will run much smoother that way.
- insert elastic: I insert the elastic after the sewing using a safety pin (see pic), but others may want to insert the elastic while sewing, I just find I can't sew as fast then and then the time difference evens out anyway. Tighten the elastic until it seems right and either tie a know or just sew the ends together. For the sheet in the picture below I made a relative small hole and didn't even bother to sew up that seem after I had inserted the elastic. It makes it easier if I later need to tighten the elastic or change it for a new elastic (lesson learned: don't used old elastic from old sheets, they dont' last as long).
