A pressing matter of strings

My guild is putting together 8.5 inch square string blocks in brights

for a group quilt.

The organizer asked for 1.5 inch white strips on the diagonal.

She suggested drawing lines marking where that first strip could go,

but I used my iron instead.

I pressed each of  foundation blocks diagonally,

and then pressed by white strips lengthwise, right sides together

I nested the strip into the valley of the foundation piece

and sewed on the first bright strip.

Here are the 16 I made for the group quilt.

I stupidly trimmed them from the back,

so in some of the blocks the diagonal isn't in the centre.

Hope the rest of you have fun stringing along.
