Hey, all, I'm trying to make a dust cover for a laser printer.
The cover is basically a cube, minus the bottom of the cube.
The top panel is cloth-backed vinyl, and the side panels are heavy upholstery fabric (I'm using scraps for this project).
The top panel will have welt cording around all four sides. (I probably don't need cording there, but I'm trying to learn to work with it, and I think it would look nice.)
The side panels are all separate pieces. Normally, I would try to use one long piece to go around all four sides, but I didn't have a big enough piece of scrap fabric to do this. So there will be a simple seam (right sides together and stitched) between each side panel -- 4 seams in all. (The side panels will have a simple hem at the bottom -- not shown in drawing.)
My concern is getting all the seams to line up properly after it's all sewn together.
I have a triple-feed machine (Adler 67) but somehow I always find a way to get into trouble!

So my question is this: Right now I have 5 pieces (or 6 if you count the 6-foot piece of welt cording):
1. Top
2. Front side panel
3. Back side panel
4. Right side panel
5. Left side panel
6. six feet of welt cording I sewed up

How should I go about sewing this all together?

Should I sew the simple (right sides together) seams between the four side panels (or maybe three out of four and save the fourth one for last) and then sew the sides to the top with the cording sandwiched in-between?

Or should I leave the simple side panel seams for last, and sew the top to the side panels with the cording sandwiched in-between ... then do the RST side seams?

Or maybe staple it all together first, then go back and sew all the seams?

Or ... something else? It just seems like no matter what, there's going to be some mismatch somewhere in the lengths of everything, and that mismatch will get worse and worse and things won't line up anymore ... so the challenge almost seems like trying to ease a sleeve into a bodice.

Sorry for the newbie question ... I just don't want to foul this all up on my first try, since I don't have a lot of fabric to play with on this.

Thanks in advance for any help.

I would sew the 4 sides together first. Then loosly sew the welt cord to the top piece. Then sew the sides on to the top and make sure its tight up against the welt cord.

I would recommend adding a radius to the top piece corners because it is very difficult to sew wilting in a 90 degree corner and get it to look good.
Also make sure to give your self alignment marks. You will also need welt feet for your machine.

Hope this helps.

Thank you for your reply, John, this helps me a lot. I figured it would be like wrestling alligators if I tried to sew the top and side pieces to the welting at the same time ... sewing the welting to the top first, then sewing the sides to the welting, sounds like a good plan.

I appreciate your help.
