I Want to keep insects out, can’t find Net Big enough??

What are you trying to cover? Screen material? Hardware or home improvement center should have what you need. Not knowing what stores you have available? What are your options so we can tell you where to look or what to ask for.

If it is screening material you need, I agree with Naomie about where to find the material. You should be able to find it in rolls that should work.

So is 69" wide? or its 1 metre 30 cm? what is it your trying to cover? a window, doorway, patio opening, bed? They make mosquito netting by the yard and some of its quite wide 72 inches (2.54 cm = 1 inch). https://www.joann.com/utility-fabric-mosquito-netting-white/10173292.html I have 4 curtains made out of this stuff that have a channel sewed on top for rods to hang, and upholstry zippers down each side seam to make a completely encased patio, make it extra long and you can add weights to keep them from coming in underneath.

Ophs forgot this one..... 13' wide..... https://www.usnetting.com/pest-control/mosquito-netting/

They have those kinds of screens for doors. They hang with Velcro and have magnetic closers in the middle. Try a search online and you may be able to get them shipped to you. I think Walmart has sold them and some other home improvement stores. They work pretty good, but are a standard size for a door. You may be able to make some yourself, too. Edge screening material, some extra heavy duty Velcro and magnetic strips will probably get you what you need.
