Once the curtains were cut out, labeled, and folded, they needed some hems. Material allocated in the rough pattern allowed for one-inch hems on all sides. For the front, sliding door, and closet curtains, the procedure outlined below is the same. For the driver’s side curtains along the louvered, rear side, and hatch windows, hems will differ slightly due to the curtain rail running through the hems. The example illustrated below is the curtain for the sliding door opening.Link to project thread
Each curtain was ironed prior to measuring for hems to make sure it laid flat. Using a material with a grid pattern aided all measurements, especially snap and slider placements. However, the grid did prove a bit challenging to keep aligned.
This fabric is a loose weave. To prevent fraying along the edges all cuts were made with pinking shears and then a simple seam sewn in behind the cut (red arrows). Not all fabrics require this step.
Each hem consisted of two folds of one-inch each. Here the first measurement and fold is made. Hem size was determined based on the late ’70’s curtains in the bus but really is up to the individual or material used. Thick fabrics may require smaller seams to allow for better gathering along curtain rails when opened.
Each measured fold was ironed flat and pinned in place.
After the first inch fold was made, it was folded over once more to keep the cut edge wrapped and hidden from view. Essentially this is a one-inch edge folded twice. Here it is pinned and ready for stitching after taking care to keep the pattern aligned between hem and curtain.
The first hem sewn in place. Looking at the bottom corner, you can see how the fabric walked a bit as it moved under the sewing machine; pattern slightly misaligned.
The first measurement for the side hems. For uniform hem corners, hem both top and bottom as a pair and then right and left sides for each curtain (or vice-versa). For the slider and front curtains, top and bottom were hemmed first followed by the sides because it allowed for a final trim. The final lengths for each of these curtains was difficult to measure, so a final trim along one edge prior to hemming helped with curtain fit.
After the first one-inch measurement, the fabric was ironed and then the second fold made and ironed. To help eliminate or, in the very least, reduce fabric movement during sewing, fabric glue was applied in the second hem fold (note cut edge of first fold behind glue line).
After pinning, glue dried for 24 hours (per instructions) before sewing (actually it just dried until the next patch of free time opened up and that took WAY longer than 24 hours)
Slider hems completed. The glue helped keep the fabric in place but some movement still occurred.
