First, I had to figure out the envelope for the situpons. So, I used a scrap piece of fabric and pins to create a small envelope. Here's my sample:
After playing, I figured out that the foldover part of the envelope needed to be on the inside. (In the background is my new Salem cutting mat and I love it. It is so big.)
Here's my testing of the turning.
Here's the finished sample. Perfect for what I need to do.
Now on to the real situpon. The cushions for the situpons are suppose to be 15" x 17" x 1". So, I measured around the measured around the length of the cushion and came up with 35". Next, I measured width along one side and one top and come up with 16". Here's the formula that I used to cut out the situpons:
Length - 35" + 1" (ease) + 6" (envelope) = 42"
Width - 16" +2" (seam allowances + ease) = 18"
Here's pics of the process and finished product:
Here's folding the envelope top with the right sides together. Because I was using a flannel backed vinyl tablecloth for this project, I used the finished edge for the edge of the envelope. Note the pin. I used 2 pins and pinned within the seam allowance which was 1/2". Next, I brought the opposite end up to meet the top of the fold (sorry, missed taking a picture). Then, I stitched 1/2" seams at a 5mm stitch length.Here's the first turn after stitching the side seams.
Fortunately, the matching sleeping bag has it's drawstring bag so I do have a pattern. The process that I used was to measure across the bottom circle. Then, I draw a similar circle adding 1/2" seams. I also measured around the bag and cut out a rectangle with the length + seam allowances and the width + seam allowance + top seam for drawstring.
Both of these projects were super fast sewing. I was not looking for perfection in either of the projects. I just needed to get them done. I was very pleased with the outcome of both projects. I think that both projects took less than 2 hours to complete from making samples, cutting out, and sewing.
I think my next project will be the curtain for the deck. This is to block the afternoon sun so that we can enjoy the deck just a little bit more in the early evenings. My outdoor thread arrived today. So, I just need to remeasure the area where the curtain is to hang and figure out the various lengths of fabric. Hopefully, this project will turn out well. I purchased a felling foot for this project. Hope it works out well.
