Fusible web problem, i think
 

Brand new to this Board...and a big problem. I am using HeatnBond fusible web, I have a Janome 6600, put in new top stitch needle have setting for blanket stitch.
Ok, the thread keeps breaking after about four minutes of sewing. I changed threads a couple of times, but to no avail.
Any suggestions? I thought the fusible web was not working due to the very humid weather, however the first time I did my pattern it worked.
I'd appreciate any suggestions before I take it to the sewing centre.

what size needle are you using?

are you using HeatnBond lit for sewing. HeatnBond ultra no sew

Make sure you are using Heat and Bond lite.. from the sounds of it you may have the wrong one!

I have never had a problem with heat and bond even if it was heavy duty-check to make sure you have a good needle for use with web-I have used top stitch and sharps and even jeans needles Good luck

The ultra heat and bond says right on the pkg that it is not for sewing. There are 3 weights of H&B.

I've sewn the not for sewing stuff. You must use a large needle that leaves huge holes. Not pretty but it works. You might try a different thread also.

are you using the correct size needle for your thread? also, like other's have mentioned- there is (sew-able) and (non-sew-able) heat N bond- heat n bond lite is the one you want- i would switch needles to a sharp or universal and make sure it is the correct size needle for the thread you are using- personally (and i've been sewing since the mid 60's) i've never had much luck with top-stitch needles- i use sharps or universals 99% of the time.

wonder under works way better.I have multiple machines and have glue issues on all of the with heat and bond-only works on straight stitch-not fancy ones.I will not ever buy heat n bond again-only wonder under-never ever an issue on any stitch or any machine.

Heat and bond is too heavy for sewing.. It is ok for crafts. You need Steam a Seam II or pellon 805 fusable. Both are light weight and easy to sew thru. Good luck

With my 6600 I always recheck my threading when I've got thread breaking. Sometimes you're missing a threading point and don't realize or your thread has come out of the tension disks. It's an easy thing to check, along with the bobbin, and it might save you a trip.

I am using heatnbond lite. Called the company which didn't help. I am using a top stitch needle, which is new. The thing is I have used this product before in projects, so it is weird that this is happening. I wonder if I could soak the block, then take some of the glue off and repress it. I have 35 beautiful flower square blocks done.

I usually use a jeans machine needle when working with heat-n- bond fusible web

OK, here is how I solved the problem. My friend cleaned my needle with an alcohol swab and said that nail polish remover would clean the needle too. So....I thought that nail polish remover on the thread would stop it from grabbing the glue. I put a swab dipped in the remover just above where the thread goes into the needle. I have had a slow haul of doing the blocks, but twenty five are done....I almost have no more remover, but it worked, with wiping the needle every few minutes. I just could not throw this work out, so am persevering then will have the machine serviced! But thanks everyone for your great responses!

thanks for suggestion on the jeans needle though. and it is all 100% cotton.
