Hi, I've sewn together all the tubes for a summer in the park quilt. I used this tutorial from Missouri Star Quilt Co: http://quiltingtutorials.com/all/sum...t-jelly-rolls/ I'm stuck now because I can't figure out how to press it... in the video she said to press flat but what does that mean? To the white fabric, to the colored side, doesn't matter which side or does that mean press seams open? I'm also a bit confused on the cutting... I realize the 45 deg line goes on the bottom seam but is the top of the triangle cut to the top seam or the top of the fabric? Any help would be great, thanks!
