Whats on the bed

I have had a little change of whats on the bed. This red and white is another find from Rennigers at Mount Dora, Florida.

It was January and the most awful grey day- raining so hard that DH and I had to wear our bright yellow plastic ponchos that you buy at the theme parks.(Got the picture) not a fashion item but keep you dry.

I was determined to go this day as you can always find something quilt related to buy and that day I found this red and white quilt.
Nothing fancy just plain and simple but I do love two colour quilts.

Puzzling thing about this quilt is it is a nine patch with interspersed snowball blocks - but as you can see the triangles on the corners have been sewn in the corner seams but whipped stitched on one edge. The whole quilt is like this and as first I wondered if the half square triangles were added to the corners as an after thought , but It couldn't have been because the blocks are sewn in to the rest of the quilt.
So their is another hidden story, Why did she do that?I have no real idea of age- probably 1930's but not really sure.
The dealer I bought it from was from Pennsylvania and that is where she said it was purchased .
