Would you cut the sides of a window seat on the bias? or is it pointless?

[Katymac]

Think covering a brick

So should the sides be cut on the boas to help with going round the corners or is it pointless/making work for myself?

No need . Top and bottom , long piece to go all around sides , clip curves , turn .
Bob's your uncle !

That is what I thought - but the piping has to be bias cut doesn't it?

Oh yes . Piping on cross .

Lovely starting to get the hang of this

Thank you

You are very welcome. Sorry for brevity but I was wrestling dinner into the grandchildren .

Kind brevity was much appreciated
