Thanks Esq. you are very kind. For everyone else, I have just finished week 9 in blocks, because I am having a ball doing them. I posted pics of the last three on my PDA this afternoon, if you want a preview, otherwise, I will be posting on these threads when they come up.
I will say here too, that I found the next triangle (Week 5) much harder than the following week (6) so if I can make a suggestion, try the week 6 one first, to get a bit experience in these inset/Y seams before you tackle the week 5 one.
