Well I think 'waste' is what ya make it!
You can learn to use the cutter in less wasteful ways.
I do not use it for all my fabric cutting as I still use the rotary cutter and my rules too!
For this project I needed stars. So I pressed my Heat n Bond light on to strips of fabrics I planed to use.
Cut out the big stars I needed.
So with more leftovers I pulled out the small flower dies to cut flower shapes and some centers that will be bittersweet berries on a border. The half flower parts work well behind other parts so do not toss those either!
As you can see I am well on my way to many other projects just from each star square scrap!
As I said at the get go the amount of waste is of your own choosing. You can toss those bits or make them work for you. If you take the time to figure out the best placement of the fabric you will have much less waste. I enjoy using the Go! to my advantage for some things I have a tough time cutting out with my sick jointed fingers! So wherever I can get that extra helping hand I do it!
I will say that the only draw back on the Go!cuts is that I can not use the Pat Sloan Do-nut method with the Heat N Bond. Which keeps the applique soft in middle.
As with any tool we use as we go along we find better ways to use it.
So I hope this has helped some see you can make that fine inch sq. go a bit further that the one star!
