well I got the wrong end of the stick, so now I am going to have to make casing for my piping first and I will have to make it from straight grain, not bias, because that is all I have got left and I will have to join some strips. I will be sailing close to the wind here. The alternative is that I don`t do piping, just plain, so I have an escape route which makes me feel better
I have overlocked a short practise strip on each long side for piping and btw the differential feed lever had been knocked up so the first side was not a good look. I fixed that and the second overlocked side is nice but I did a wide 3 thread overlock and a narrower one would be better
I pinned some piping into the strip and it does bend nicely around a corner, the fabric weave helps. I have to wait for the piping foot to arrive but doing some practise samples is good. I thought I had had a good look at the original cover piping but had not noticed that the two edges had been overlocked together
I am not sure if I have a piping foot for my overlocker. I will have a look soon and if so, have another practise to see if I can do the same. It would make it easier. I am not using the cutter on the overlocker, it would get blunt, the fabric is thick
I will probably have to re-think the dimensions on the top, bottom and side pieces as I don`t want to use the cutter. I will probably have to stick with 1.5cm seams, I had been minded to use the cutter to get a very neat edge but I will do a mini seat cover first, very mini with no zip
The zip placket will be the easiest and I will insert the puller after the zip is sewn in. Some areas of the sides are going to be pretty thick because of joinsin the piping strip. I have a babylock overlocker, at least 16 years old now and it is a very strong, reliable machine. Overlocking both edges of the piping will flatten it down a bit and make it easier for my sewing machine when it comes to final assembly
I quite like all this new learning btw
