You need camping permits and reservations to stay overnight on the White Rim and there is a good chance there aren't many available sites in March.  Check the NPS Canyonlands website to see what is open and then update your post with the campsites you hope to use.  That basic info will make it easier for us to help you.  Good luck.

Great setup Mark.  Your top tube bag is really impressive.

The  Sailrite is a very good machine and a great choice for bags and packs.  The Singers will handle lighter fabrics like silnylon, lightweight nylon, cuben, etc with less fuss so pick one up if you want to makes tarps, quilts, or clothing.  201's are classic machines and really well made but quit old.  Ask the seller if it has been rewired before purchasing.  If it hasn't you can do it yourself but it's time consuming.

Two classics.  Get the Rocketeer if it comes with the cams.  Both are great machines but the Rocketeer is a zigzag machine which will allow you to bartack.  The motor on the 503 is stronger as well and will handles multiple layers of heavier fabric and webbing better.  

Either of the two will be ok but have you considered a vintage machine?  The older machines from the 1960's and earlier used all metal gears, are easy to maintain, and have enough power to handle the fabrics and thread you will use making bikepacking gear.  Modern machines are made with plastic parts which will wear out especially if you work with heavier outdoor fabrics and webbing. You don't need all the stitch patterns they come with and can get by with a straight stitch machine or one with zigzag capabilities which will allow you to bartack.   The old straight stitch Singers like the model 15's, 201, and 66 are easy to find, restore, and parts are available if needed. The Singer 401, 403, 501, and 503's are all metal machines with zigzag which show up often on Craigslist.  There are lots of other quality machines from european manufacturers too....  Necchi, Pfaff, Viking Husqvarna, Elna, Bernina, etc.  You can search the net and find info on the various models that you spot.  Read the reviews before buying.

Backpackinglight.com and hammockforums.net have quite a few posts on machines and gear making.  This guys videos and threads are quite useful and worth checking out.  http://www.hammockforums.net/forum/showthread.php?t=19006

I spent most of the last 3 months on crutches and it sucked.  I hope your leg heals quickly.

That sucks.  Tanner is a great guy.  

Sold pending payment.

New Golite women's winter Adrenaline 0 down sleeping bag. 800 fill, regular length, center zip, 9  inches of loft, rated to zero Fahrenheit, and weighs 2lbs 14oz.  It has been stored uncompressed.

 $200 plus shipping and PayPal fees.

It's a nice classic straight stitch machine and should be adequate for most of the thread, fabric, and webbing you'll work with.  Read the manual, oil it up, and give it a try.

Downlinens has a great selection but sells by the pound.
Quest Outfitters  - 900 fill
Ripstopbytheroll  - 850, 800, 750
Wildernesslogics  - 850

As others have said, just tuck the edges in and sew it together.   The quilt shown below was made from 1.1oz nylon, 900 fill down, and noseeum netting.  The netting was sewn edge to edge on both the top and bottom fabric.   It's over 4 years old and has seen heavy use.  The fabric hasn't frayed and the down hasn't migrated between baffles.

Justin just passed through Boulder.   

I didn't see anything in his rules write-up but Roy Benton did it as a loop so Justin will too. 

It looks like he has reached the summit of Long's and broken the record! 

You're right.  I forgot about Longs.

He just knocked off Front Range and only has Torreys, Evans, and Bierstadt left.  I bet he finishes today.  The guy's an animal!

That's a Singer model 15, probably a 15-91. It's a classic all metal machine which will handle the webbing, fabric, and heavier threads you'll use making gear.   It's easy to service and replacement parts are available and inexpensive.  Buy it if the price is right, $50-75 for a working machine.

Good question.  One of Colorado's finest told me that wood fires including those in the hobo type stoves you're describing are not allowed when the bans are in effect.  He said that they were banned because there was a chance that sparks might escape from the unit or the user might accidentally dump live embers after cooking.  Another told me that they are considered stoves and allowed.   I'd call the county government for the area that you're planning to visit and hear their opinion. 

As to how to build one....there's the traditional method:
http://www.motherearthnews.com/diy/how-to-make-hobo-stove-zmaz84zloeck.aspx#axzz32OdY2qo2

or the Mr. Natural method which doesn't require a can and will get the local rangers riled:

Find three stones and form them into a U, build your small fire in the center, and lay two tent pegs across the top to serve as a grill.  You can space the stones closer together so that your pot, cup, c-rations, etc sits on them above the flames and ditch the pegs if you're really into ultralight bikepacking. 

29ers are great but at your height a hardtail with 26 inch wheels would probably be a better choice for bikepacking especially if you're traveling internationally.  As others have pointed out, 29er rims and tires are currently harder to find outside of the US.  You'll also find that small 29ers limit the amount of gear that you can carry on the bike.  The front triangle of a 29er is smaller than that of a similar sized 26 inch frame so you'll have to run a smaller frame pack with less capacity.  You'll also have less clearance between the bottom of your saddle and the top of the rear tire which will probably force you to use a small or custom medium saddlebag, you won't have enough clearance for a large saddlebag.  If you run front suspension the distance from the underside of your handlebars to the front tire will limit the diameter of the load you can safely carry.  You can use racks and panniers instead of the current soft packs to carry more gear but the setup will be heavier and some riders have had problems finding systems which provide adequate clearance between their heels and the panniers.  

Another reason to go with a 26 inch bike is the current state of the used bike market.  29ers are hot, 650b's too, so it's pretty easy to find quality used bikes with 26 inch wheels selling for really reasonable prices.   Good luck.
