We all three ended up with Keens:

I was thinking that you could probably do this same kind of activity with all kinds of things--sea life, trees, cars. How awesome would it be to draw a life-size picture of your house, or a blueprint of it that shows all your rooms and your furniture?
But you could leave out all the junk that's all over the floor, probably.
1. Using a satin stitch (or a zig-zag stitch whose length is close to 0)-- --stitch across the two 11" sides of your complementary fabric. This will finish the raw edges, and it gives a nice border to your fabric.
2. Lay your home-dec fabric face-down on a gridded cutting mat and lay the complementary fabric on top of it. Both fabrics should line up along the 11" length. For the width, however, the complementary fabric should stick out 2" farther than the home-dec fabric on one side (this will be the top, if you want a pattern to face a certain way), and the rest of the extra width will stick out from the other side.
3. Fold both sides of the longer complementary fabric so that the folded edge is even with the raw edge of the home-dec fabric (you can iron this crease or just finger-press it), and pin it into place.
4. Satin stitch around all four sides. This will close any remaining raw edges, and give you two pockets running the entire length of the fabric, a 2" wide one at the top and a wider one at the bottom.
5. Lay your crayon roll back on your gridded mat with the complementary fabric facing up and the 2" wide pocket at the top of the roll. Across the wider pocket, from seam to seam, mark a straight line with a pencil from the top of the pocket to the bottom every 1.25".
6. Sew over these pencilled lines, locking your stitches at the top and bottom. These are the pockets the crayons will fit into.
7. At either end of the crayon roll, sew your elastic. Fold it in half and use a zig-zag stitch with a length set to 0 to sew the elastic to the crayon roll.
8. Insert crayons and give it to somebody to color with.
I have a few sets of these rolling around the house to throw in a bag when I'm going somewhere with a kid, and I also give them out as birthday and Christmas presents and sell them at craft fairs.

--and then go home and I go out shopping (I bought 16 Kashi frozen pizzas. They were on HUGE sale) and Matt feeds the girls dinner and they con him into letting them watch Land Before Time, and NOW they're finally asleep, and I'm trying to figure out if I'm too tired to make myself a smoothie, or if I should just watch Step Brothers with Matt until I fall asleep, too.
And tomorrow we're going to garage sales, baby.
We've got some awesome dino-lovin' activities planned for this summer. We'll be practically in the front row for the Walking With Dinosaurs Live show when it comes near us in July (we're having to forgo our traditional huge summer birthday bash to afford the tickets, which are OUTRAGEOUS, but it's going to be worth the budget re-allocation, I know), and do not worry, I've already mapped out the locations of the dinosaur museums that we can visit on our June trip to Wisconsin--the Milwaukee Public Museum, the Dinosaur Discovery Museum in Kenosha, and the Field Museum in Chicago, likely. Wisconsin is light on dinosaur museums because it doesn't have a fossil history because dinosaurs never lived there because it was covered in water during prehistoric times; this is what you get to learn when your children are obsessed with dinosaurs.
We'll also have the time and the nice weather to do some other dino activities that require more time than the big kid's three-hour daily preschool would allow (three hours doesn't seem that long while I'm living it, but I have to plan my whole damn day around it!). Whenever we can wrangle my partner (I'm begging him to ask for flex-time at work this summer. I really want him to work four ten-hour days instead of five eight-hour days, and since he's a designer, he actually could use the extra time at work in the evenings, no phone calls, no visitors to his cubby, to focus on his designs), we're going to make measurements on the basketball court over at our neighborhood park and then draw life-size dinosaurs in chalk (this Smithsonian handbook on dinosaurs is our most precious family resource!), and I also want to score a load of helium balloons on some calm day and use them to measure out dinosaur heights in the park--ooh, I'll also need a lot of string.
We go creek-stomping around here a lot, and the kids enjoy searching for geodes and crinoid fossils (the big kid claims that she is "the best fossil hunter out of all my friends," and I have to say that it's probably true), so depending on how interested they are, it would be fun to add on more of that into our dino activities. Where we live in Indiana is actually a superb place to explore for fossils--a shallow prehistoric sea left lots of little ocean critter fossils, and a glacier later on the same site kept the bedrock from being too covered with subsequent layers of earth, so now you can easily fossil hunt (where it's legal) in most creeks, road cuts, and limestone quarries (but not caves! All the Indiana caves and sinkholes are closed to the public this year in hopes of stopping White Nose Syndrome from spreading. Sucks).
Perhaps we could even find a brachoid!
