Tools other than sewing machine?

[WaffleBox]

Howdy folks! Due to a very recent, as of yet unannounced development, my need to get into DIY has become official. Apart from a sewing machine, what other tools should I invest in? Do you have recommendations for particular brands, etc? Here are some of the projects I'm likely to tackle over the next few months/couple years in approximately the order I would tackle them in:

-Modifying a silk sleeping bag liner into a top quilt shape
-Gathered end hammock with knotty mod on one side and cat cut on the other 3
-Sheltowee-style bug net
-Summer underquilt (probably apex but maaaaybe down if I'm feeling gutsy)
-Large tarp with doors, silnylon or silpoly
-Down top quilt
-Cuben tarp with doors

Some of the things I'm thinking I might need include (please feel to add to the list or tell me if something isn't that useful):

-Rotary fabric cutter
-Large self healing cutting mat
-Fabric shears
-Thread cutters
-Seam ripper
-Long, transparent ruler

I'm sure there is a lot I'm forgetting. Please give me any suggestions you have. I appreciate it!

Most of us need a seam ripper sooner or later.

Thanks, I'll update the list in the OP to add things as people make suggestions. Recommend any particular seam ripper?

A long transparent ruler helps with what you have already mentioned.

Extra Bobbins
Bobbin winder
extra needles
lots of thread
large flat work surface ( I use a 6ft long table with two cutting mats on it

As expensive as cuben is you are almost better off buying the finished product.

That's part of why it's the last item on the list. It'll give me time to decide if I really want to make one or not.

Chalk or some kind of fabric marker.
Perhaps pins?

It is really inconvenient to have a bobbin run out in the middle of a long stitch and then finding out that you don't have any more bobbins wound with that thread. It's a good idea to buy two spools of thread and have a way to wind a bobbin while your sewing machine is set up for the piece that you are working on. A bobbin winder would do. I have an old machine that doesn't sew well, but winds bobbins very quickly.
