    Ok, still being a newbie in the quilting world, I honestly do not know the answer. Is there an advantage to using a 60mm rotary cutter over using a 45mm? Does the 60mm cut through more layers of fabric more easily than the 45mm? I ask, because I am always trying to figure out better and less time consuming ways to cut. Thank you in advance. :)

    I have both but use my 45 most of the time esp. since I found rotary blades at harbor freight for really cheap.I also don't cut more than 2 layers at a time because I have learned the hard way that one of the most important things you do it cut accurately!Nothing else matters if your cut is not spot on!

    I was actually hoping that the 60mm might eliminate the little dips in the fold of the fabric when cutting more than 1 layer at a time. I will not use anything that does not have straight sides, therefore I end up with more fabric waste than I want.

    I use the 60mm. It seems to be easier on my hand and wrist.

    It won't eliminate the dips,I could be wrong and I am not sure why the dips occur in long pieces.I know if I cut 12 in. or less I don't get dips.

    45mm blades are a lot cheaper than 60mm ones. 60mm are usually used when cutting many layers of fabrics. You get the dips when the folds are not straight--doesn't matter what size blades if the folds are not straight.

    28 mm here, didn't care for the larger blades, to me less control, 8 layers no problem.
    But that's what I started with, could be why.

    great, thanks for the info. funny thing is i thought my folds were straight, but i guess that is what i get for thinking. lol so, i suppose my next question would be "how do i ensure the folds are straight". i spend the extra time to sooth, sooth, and resooth the layers and folds out. what is the trick? :)

    I use both but yes, the larger ones are more expensive. I use my 60 a lot more I noticed.
    It cuts so easily for me.

    45mm is just a smaller blade to cut thru a few layers.. the 60mm will cut thru quite a few more layers than the 45mm. its all a matter of preference. Some think the 45 is easier to handler and others like the amount of fabric the 60mm will cut.. I have both and the 28mm for smaller cuttings that are more rounded.. Its a try it and see kinda deal..

    I have one of each for sale if anyone is interested (listed in the classifieds..found them when I was cleaning my sewing room)

    Quick Change Olfa 45mm & a 60mm

    You just have to make sure the fold on top and the fold underneath are together and straight. You also have to make sure your ruler is straight also. I'll look and see if I can find a tutorial on avoiding the dips.

    This article shows how to make sure your folds are lined up correctly: http://www.how-to-quilt.com/articles...straight.shtml

    I have both, but prefer the 45. I just seem to be able to control it better. May be all in my mind.

    Dips? The elbows at the fold? You have to get those selvage edges lined up to avoid elbows.

    If it's in your budget, invest in both the 45mm and 60mm rotary cutters. You'll use the 45mm for cutting, trimming, squaring up, etc. The blades are less expensive and easier to find. Change those blades often. Dull blades make for grumpy quilters.

    The 60mm would be great for multiple layers, trimming quilt sandwiches, and more. If you can only invest in one cutter, get the 45mm and buy lots of spare blades.

    I'm currently testing out the Martelli cutter and it's been great so far. Less wear and tear on my wrist.

    I've been quilting 20 yrs and never used the 60mm. and hardly used the smaller one 10mm i think it is. i use that to rip out stitches when necessary. mostly use the 45mm one for everything.

    i had the same problem (sew in a motorhome w/no slides) when i ask the lady at lqs and she said to make sure and put pressure where the fold is and it will help. so far it has helped with my cuts.

    I use a 45mm one, and love it! I feel I have better control, and can cut at least 8 layers of fabrics no problem. An added plus is that you can buy blades at Harbor Freight at a very decent price!!

    I prefer the 60mm also for the same reason.

    I use to have that problem. I solved it by buying a bigger cutting mat so I only have 1 fold. It may take me longer to get everything cut, but at least there is no more waste. I still use the 60mm cutter. That is what I started with and still use even though I'm only cutting 2 layers.

    I use the 45mm blade. I also use the Fiskars handle that is a lot easier on my hands than the upright ones.
    I seldom cut more than 4 layers at a time because I find the fabric shifts unless I put a LOT of pressure on my ruler.

    have been using both the 45 and the 28 ...... but i tend to get carried away with the larger cutters, and put notches in my fingers ..... specially with the larger blades. have just got an 18mm cutter and gonna give it a try and try saving my fingers. and fingernails. it would probably behoove me to change my hold on the ruler, though

    Do any of you who have orders for blades from Harbor Freight that are on backorder received them yet? I haven't. I just emailed them to ask about it though.
