@Cody Lunning If you install the lower cover first and then dry fit the back rest, make reference marks on the foam or cotton layer. They will help you align the back rest cover along the lower edge to mate with the bottom cover design.

Working from absolute center outward will also help with pattern alignment issues.

Also remember that the upper cushion comes over the bottom about two inches and the dimension of your pattern will be different from the outer edge. Call me if you need more help.

Thanks @Fred Mattson I’ll give these bits of advice a go. Have to order more material first. It’s crazy as I’ve done things where they clearly have to line up top to bottom and have no issues or an issue I could correct easily anyways. This seat is just fighting me and thought I’d ask to see if I’m doing something wrong.

Don’t know if pic uploaded sorry.
Firstly I’d just like to say I don’t like to pick fault with anyone’s work as we all have off days.
However I don’t know if this will help you but there is a fault between the two sides of the Squab (seat back) as the diamonds are not matched (iv circled the area in image) so wondered if maybe you had taken up too much Seam on one side causing it to sit wrong.
My method would be as previously mentioned and dry fit against cushion and mark your centre point so when cover pulled on you can reference it.

@paul thundercliffeno, I can handle critiques. It helps me to improve. No worries. The seat bottom in this picture is actually the back as I had that laying down and holding the real seat bottom and it appears to be the back. Sorry if that’s confusing lol. But the seat section you circled is actually the one I’d redo. I’ll try to focus on them being even like you suggest.

Is the middle strip centered? It looks like it may be wider on the left than the right side of the vee.

@Lew Mutchler I tore that cover off to start again. I’m fairly certain that aspect is centered correctly but I do see what you mean. I feel it’s the visual of the whole thing off to the left, that’s messing with this picture. But it is off like Paul mentioned.

@Cody Lunning I am sure you will nail it this time. You do good work and taking the time to make a project better is golden!

@Fred Mattsonthanks Fred. Luckily I know this person pretty well and can be honest with them saying the outcome wasn’t the best and I want to try again. They understand. I mean I’m honest with everyone, but some don’t like the wait.

On a side note, where the red triangle section comes to a point. What does everyone do with the seam allowance here. I trim it before adding the beauty stitch so it doesn’t have a bulge after the first hidden stitch. Hope that makes sense

Got it finished. 3rd time is a charm I guess.

@Cody Lunning Fantastic!

@Fred Mattson thank you!

That looks awesome! Great Job!

Perserverance pays off. That's one of an auto trimmer's most unique assets - patience!

Hi Cody, just thought I’d chime in on your question about the top stitch on the center triangle section. We would always leave the seam (on) for top stitching as it gives a much more stable surface for your foot to sew on. If you are using scrim on your fillers we cut the first outer stitch on the inside and trim back the foam first (reducing bulk). Then once you have top stitched you can trim back the salvage at this point. When it comes to a point(triangle part on your seat) you can mitre the seam prior to the top stitch so as to avoid any pinching of layers underneath. Hope this is of help and makes sense with my long winded explanation As a side note to this way of doing it , we find that this has the opposite effect to what you are trying to avoid (Fat bulky looking top Stitch) so depends on what you are going for.
