Hi, all!
Here's the heart pillow I created while following along with the Cloth Properties and Cloth Dynamics video lessons.
I struggled a bit with the internal heart shape that was supposed to serve as "stuffing" for the pillow, no matter what I did it kept poking out through the pillowcase. As a workaround, I added equal positive pressure to the pillow pattern pieces, deleted the interior "stuffing", and everything worked out just fine, kind of.
As you can see in the image above the pillow won't lay flat, the curved edges of the heart sit lower than the point which always seems to rise up. Does anyone know why this might be happening?
Thanks in advance for any help you can give!
Update!
So I gave this assignment another go and followed the directions to the letter, mostly. Here's the result.
I noticed there was a gap in the "cleft" of the heart when I sewed on the puffy frill, for this reason I tweaked the pattern a little bit to allow for a bit more space in between that area. That seemed to solve the problem. I'm much happier with the end result now.
Additionally, I just finished the banner assignment; you can find the finished product below.
I took some liberties with this one as well; I wasn't satisfied leaving the tab top (the 3 strips of fabric wrapped around the rod) with the interior of the fabric showing so I duplicated those pieces, sewed them together, and then affixed them to the top of the banner.
If you were actually sewing something like this, you wouldn't leave the rear of the fabric exposed. For the same reason, I duplicated the front of the banner and sewed it to the back. Doing so ensures both sides are uniform so if this were used as a game asset it could be viewed from any angle and look great, and it also eliminates the need to "hem" the edges as demonstrated in the video.
I decided against modifying the size of the strip of gold fabric on the interior as well; making something bigger fit into something smaller requires easing the fabric together. This has to be done when you're sewing something like a sleeve cap into an armhole or even sewing the side seam of a pant leg (the rear portion of the pattern is always slightly longer to account for the extra fabric you'd need when you bend your knees). While not as interesting looking because it lacks the extra folds shown in the version created by the instructor, it's more technically correct and better sewn from a practical perspective.
