Michaels has scrap booking wheeled cases. They are not too pricey. I know someone who uses it for toting her machine as well but not often, not sure it will hold up for that. I think that the plastic cases are made to fit these. Have fun sewing. My 25 year old son still lives home so I don't have a sewing room either. LOL

During winter months, I sew in our bedroom & have to keep things compact & picked up! I store fabric & supplies in long plastic containers that fit under the beds. I use stackable plastic containers for other quilting things, magazines & etc. I purchased a wheeled tote with slide up handle to take my machine back & forth. I have room to set my machine in & pack accessories box, cords, pin cushion & extra fabric & stuff around machine. There are side pockets for cutters, scissors & large front pocket. I store rest of stuff in tote & set on top of zippered case & wheel it along.

You can also find the wheeled type cases/carts at office supply stores. They're pretty basic, but depends on what you want.

It sounds like there is just a problem with keeping everything neat and tidy at the end of the day and not just getting to classes. I don't know what your financial situation is but have you considered something like this? http://www.sauder.com/Sauder/Craft-F...re/158097.aspx
There is quite a bit of storage and two doors to hide everything behind. There are places where you can get something similar for less money. Just be sure and check out how far the doors swing open. I have a computer desk and the doors opened to 45 degrees and not clear back out of the way.

I have one of the large scrapbooking totes like your Mom's. I think it came from Michael's and I really like it. I know some people found they broke theirs but so far mine is great. I pack it to the brim when going on retreat, but I do not use it for my machine. I store it back in it's box when not in use. I usually just carry my machine, but I have used the old fashioned suitcase trollies when at a conference where we had to take our machines to different buildings throughout the day. Might find them at a 2nd hand store for low cost. This is similar to my luggage carrier wheels. https://www.google.ca/search?q=suitc...hp%3B325%3B269

I use those square fold ups that WalMart sells for $19.97 in the office supplies department. My machine fits inside one with extra room for an extension cord and/or iron. For my tools I use a Tool Bag with a shoulder strap (it has several pockets inside and out for holding tools). I keep projects I am working on in 2-gallon Ziploc Freezer bags, they are very strong and can be used repeatedly. The 2-gallon bags are large enough for entire projects and are tall enough to hold instructions/magazines, keeping each project together (I was misplacing magazines/instructions before). Lowes has some great items to hold small sewing necessities.

Stanley Tools makes a great rolling tool box (Lowes or Home Depot) with an upper compartment for tools and a lower bin that would hold fabric, WIP, etc. $34.98 online. They make another for $79. Here is a link.

You might want to look at wheeled toolboxes Home Depot has Stanley's Fat Max--I understand they come in different sizes. I love my Fat Max, but you have to watch how much fabric you pack in it because of the weight when loading it into the car.

Wow - I hadn't seen anything like that as reasonable as that one. Great idea.
