I have the AccuQuilt Go system. I have 12" qube with the 2 accompanying qubes. This will allow you to make an infinite number of blocks that can actually finish larger than 12" in some cases. I have all 3 cutters for the Go system. I started with the Go (larger crank), and moved up to the electric since I have a rotator cuff problem. Once I placed an order large enough to get me a "Go Me". All of the qubes will fit in the smallest of their crank machines. A setup like this and a few strip cutters to include 21/4 or 21/2" strip die will give you binding. With a strip die you can cut a bazillion squares by subcutting the strips. You can make triangles, 45 degrees, and 60 degrees.
I've come to the point I'm done with buying dies unless it's a block on board I HAVE to have which may never bee the case since I have a qube setup. They seem to keep having fantastic sales but it seems like a good one they don't include mats. You have to have a mat to make the cuts. The only way to get additional mats is to buy them. Only qubes come with a 6x6" mat. Mats do wear out over time. It seems lately they only are coming out with applique shapes that are of virtually no interest. I have no children or grandchildren to sew for.
I've noticed lately they no longer "register" your dies you purchase directly from AccuQuilt. That means you'll have to make your own list or print out your current dies or they'll catch you and you'll order a double if you're not careful. It seems they're making it more difficult to return duplicate dies, I'm hearing that many LQS that do carry AccuQuilt are quitting because they can't compete witth the sales and promos that AccuQuilt keeps having. Shipping used to be $8 until our shipping problems started. Now it's $12. This only started when the post office raised their rates. They have always used FedEx for delivery and still do so why a $4 increase is rediculous IMHO..
There are thousands of free patterns on their website. You don't have to have the size qube that is mentioned, all qubes have the exact same dies, just larger or smaller. Qubes come in 4, 6, 8, 9, 10, and 12". If the pattern calls for a 6" qube and you only have the 10" then yours will just finish larger. You will also be able to cut up to 6 shapes with one pass of the die. If you have the electric cutter you can feed 2 6" qube shapes at a time.
