How do you shave a jumper?

[Mysterian]

It's gone bobbly. I don't have access to an electric one, just a Gillette razor with loads of blades in it. Any other way to remove bobbles?

I bought an aldi bobble remover, battery operated, best £5 I ever spent. I'd be worried about damage using a razor

I bought a 'Steamery' and it is very effective. All my jumpers are now bobble free and look like new.
The manual combs just didn't work that well IMO.

£5 seems a lot for something I'm going to use once every couple of years. I'm more of a fleece person than a jumper one. Maybe if I then let it be known I have a bobble remover I'll get requests to borrow it. Make new friends, etc.

Wrap parcel tape round your hand sticky side out.

I have a Philips fabric shaver - use it all the time. It’s good for all fibres and I use it most on cotton

I do that for fluff. Is it strong enough for bobbles?
