They also make great gifts. I made this one as a way-early Christmas gift for my sister-inlaw-inlaw-inlaw.
This instructable assumes you have basic knowledge of sewing.
Step 1: Materials
-Some cotton fabric, or a T-shirt you don't want (in this case, a t-shirt)
-Something to put inside the hotpod. There are lots of options for this. I'm using wheat berries that I got from the bulk foods section of the grocery store. It takes about a pound. You can also use oat seeds and regular (non-instant rice). Whatever you want to use, just try microwaving a little bit of it first to see that it doesn't burn or smell gross.
-Optional: some nice-smelling stuff to mix in with the seeds. A couple bags of your favourite tea will work nice.
Cost: $2 for the t-shirt (Anchor Blue was going out of business; you can also get cheap shirts at Value Village or Goodwill), $1 for a pound of of oat wheat berries (and I had a little bit leftover), and a couple bucks for the tea. Total: $5 - $6.
-A sewing machine. Or just a needle and some thread, if you're hardcore.
-Some scissors to cut the fabric
-Some scissors to cut thread (could be the same pair of scissors, I guess)
-A scoop of some kind, or a small bowl
-Optional: Some music to keep yourself entertained.
Step 2: Sewing the First Two Lines
For the one across the bottom, though, do not sew all the way across. Leave enough room at the end for you to reach your hand into it without stretching the seems. Take a look at the picture to see what I mean.
Step 3: Section Into Fifths
Doing this keeps the filling more evenly distributed and keeps it all from falling into the ends.
You can measure out the width of your shirt with a ruler and do it that way, but it doesn't need to be exact; as long as it looks like 4 or 5 even sections to the eye, it should be good enough.
Step 4: Add Seeds
Now, pull a scoop of seeds out of the bag. It doesn't matter if you use an even scoop or a heaping scoop, just as long as you're consistent and put the same amount in every time.
Stick the seeds in through the hole you left in the bottom of the shirt. Then, pick up that end and let all the seeds fall to the other end of the shirt. You want to get all the seeds you just poured in to the section on the other end of the shirt, so feel the shirt to make sure there aren't any stuck in the fabric.
Once they're all in there, clamp off that end of the hotpod with your hand and just feel it to determine if it's the right amount of seeds. If it feels like it needs more, add another scoop. This is just a matter of preference, so go with whatever feels right. For the one I made, each section has 2/3 cup of seeds in it.
Step 5: Sew Up the First Section
Remove the pin or whatever marker you used, and then sew a straight line across (the green dotted line in the diagram), to seal off that section.
Step 6: Repeat for the Remaining Sections
Keep doing that until the last section . After you've put the seeds in the last section, finish by sewing closed the hand-hole that you left open before. Now, the hot pod should be completely closed and sealed off.
