Coming up in the triangle LS 10, this seam isn't quite a Y seam as there is no seam leading to the pivot point. I tend to tackle these a different way, working from the pivot out. First determine where the pivot point is.
Line up the two patches, using a pin to get the pivots together, and stitch the first side from the Pivot to the outside edge.
I have used contrasting thread so you can see my stitching, and I also do two or three backstitches when starting, to strengthen that part.

Once the first side is stitched, snip the purple fabric to within a thread or two of the pivot point. This will allow the purple to pull open so that the second side can be stitched.

To start the second side, put the machine needle back into the pivot point. You will have to pull the purple around so that it can be lined up with the white section. Some creative origami to the left, to get rid of the bulk helps, especially if you are PPing as the paper adds extra bulk.

Pull gently so that there aren't any creases towards the pivot, line up the two edges, and stitch as before, doing one or two back stitches again to strengthen the area where you snipped.

Thanks Lesley, I love the idea of starting at the pivoting point!!

Ta Dah! one completed inset seam. If you do have a little wrinkle near the middle, it can often be steamed into submission with the judicious use of an iron.

Thanks Lesley, you are a star.

Nice tute Lesley!! Thanks! Which week is this one for the DJ?

LS 10 is the triangle for week four, and has two inset seams just like this one.

RS 6 is the triangle for week five, but I recommend that you try TR 9 from week six first. They both have Y seams, but TR 9 has less of them. You can use this inset seam method for Y seams, still starting from the pivot point and working out. You just eliminate snipping to the pivot point. Instead, undo a few stitches from the central seam (the bottom part of the Y). Hope that makes sense.

Great tute Lace!!!!!

you can put the pivot point in on the y seams as well, it is where the three seams come together. the only real difference is that the shape is made from two fabrics instead of it being cut out of one. so this can also be done in one seam but some find it easier to do it in two,

Excellent!!!!! Thank you SO MUCH!

If you take a scrap of spare fabric and cut the shape of the purple fabric, then put that central snip in it to the pivot point, you will be able to pull it into a straight line. You can then see how it is possible to sew another patch to it, there is just the problem of folding the bulk out of the way while you do the sewing. I hope that helps you to 'get your head' around the problem.

lacelady you rock!! :-)

Thank you... that's perfectly illustrated. I'm having a day of sewing today, I'm going to have a go at the Y seam and this one too.

Well done Blue, go for it!

Thanks Lesley for the great tute! I staggered onto LS10 and finally got it to go together with a little twisting and turning and choice words. The iron came in real handy too!! Should have waited for your tute. I'm tackling TR9 next. Whew! Wish me luck!!

Wonderful tute!!! Thank you so much :D:D:D

Best of luck Jan, let us know how you get on!

Anyone know how I can print out this tute? I want to take it to a class I'm going to and won't have internet access...

Short of hitting File, then Print, sorry, no I don't. Plus I have a nasty feeling that if you do do that, it wants to print every page. At least this one is only two pages long. Best of luck.

No, it prints either people's avatars and some of the ads or nothing. Can't get it to print out...grrrrr

Copy and paste?

you should be able to highlight just what you want to print...select print and when the print box appears, select "print selection".

Leslie...Thanks for the great tute..I'm finding that I am having trouble with all the bulk and trying to pull it out of the way. It wants to leave all these bulges and wrinkles...GRRRR!

And Rach...I have had good luck printing when I highlight the "posting sections" only, then file..then print.

I'll try your suggestions ladies. Thanks.

Leslie, My block came out great using your tute. Thanks!!!!!

You're very welcome. Sorry Sandpat, you have to do quite a bit of folding to hold the bulk out of the way, especially if you are PPing.

Thanks for the info, i made the block by machining the first part and then hand sewing the second, but I am off upstairs to my lair to have a go as it again!

Yes..you are right...lots of folding, shoving and holding your mouth just right...but it works!

Well done for persevering!

LOL, ain't that the truth. I'd hate to have someone snap a photo of me at the wrong moment!!! I know I tend to purse my lips sometimes and it looks totally dorky!

It's only an aid to concentration, just like when people stick our their tongue when they are drawing.

My Mom used to tell me that was the problem when I would tell her something wasn't working...she'd say, "you aren't holding your mouth just right"...silly isn't it??? :lol: :lol:

LOL :D :D :D

What a clever tute, Lacelady. Thanks so much for sharing. I'm not doing the triangels...yet but someday I'll want to add them to a different quilt, I'm sure and in the mean time, I'm sure I'll find another nasty Y seam to practice with.

thanks for the tutorial, wow
