Portable Sewing/Quilting Kit-What am i forgietting??
 

I am making a portable quilting kit. It will be like a roll that I can take along with my sewing machine to classes , work project at church etc. So far I have included:
Sissors
snip sissors
treaded bobbins
marking pencil
pencil sharpener
1/4 inch ruler
3", 6" squares
Stitch ripper
blind threader
thimble
sewing machine needles
hand sewing needles
pin cushion
tape measure
pin cushion
rotary cutter
rotary blades
striaght pins

So what I am I forgetting?

A rotary cutting mat.

Spool of thread for machine

I usually forget to take my glasses and then end up squinting at my stitches!

Fabric glue stick. I also keep one of those pointy things you use to push your corners out for applique in my carry along kit. Will you need to tote along an iron?

I'm not in the same room as my rolling cart so here are other supplies I can remember that I take in it.
--Sewing Machine+ foot pedal+ electrical cord+ the foot or more that I'll need.
--Pattern, Fabric, Thread for that day's project. Those cannot be borrowed!
--Pins...straight and also safety pins
--Pin cushion you mentioned, but with my magnetic one, I never drop any pins.
--Cutting Mat.......I have the kind with an iron "board" on the other side.
--Rulers..... that fit or can be secured outside of cart......you just never know what you might need.
--Masking Tape.... it can help mark any size seam allowance ie 1/4" or other, also can help hold on binding,
also can use to make your sewing line instead of chalking or marking.
--Pencil,pen, scrap paper... for notes to pin on ie block pieces
--Piece of white Paper or Batting.....put behind needle to see the thread better for threading (if machine doesn't do it).
--Reading Glasses or small Magnifying Glass to keep in kit (never take out at home!)
--Thread Catch-All......piece of batting or felt...it's easy to toss when time to leave.
--Small Screwdriver.....in case thread gets really stuck
--Instruction Book for machine (lies flat on the bottom of case)......to troubleshoot or be reminded how to do tasks.
--Iron.... I have room in my cart (a tapestry-looking "bag" that zips).
--Extension Cord in case the plug is too far away for my machine's cord to reach.
--Bunge Cord connects a secondary, smaller bag on top and secures the cutting board and tall ruler.
--My Rolling Cart came with another smaller bag + a flat holder (opens like book) with plastic pockets for small items.
The book fits inside the case. Everything else is kept in zip-lock storage bags,heat-resistant iron holder-bag too.
--When I get to my Quilt Club, it takes 2min to bunge-cord the second bag etc then I just walk with my easy-to-pull
rolling cart. So far, I've never been without a tool. I'm careful to always retrieve anything someone borrowed.

A 24inch ruler for long cuts. Plasters, mug sandwiches.
The number of times I forget sandwiches because I hate eating them after they have been made for a few hours.

Small screwdriver, long tweezers, and needle nose pliers have saved many a day sewing away from home. I also take a power strip with long cord. I keep the round one that rolls up a 25 ft cord in my car trunk. I keep a small power strip in my sewing machine rolling cart. I keep duplicates of all my sewing supplies in a case in my car. I never have to pack to go to a workshop or sewday other then fabric and pattern.
But I got to sewdays/groups/guilds/workshops/classes at least once a week. I'm going to one today as soon as the other Nana gets here to take charge of the greatest grandson in the world! I take care of him during the day so he won't have to go to daycare. He's so stinking cute.

A small bottle of fabric glue in case you snip your fabric too far; a couple of band aids so you don't bleed on the fabric

The manual for your machine in case it decides not to play nice you can trouble shoot the problem.
