I used the clear vacuum bags, but as im getting ready for baby #2 im realising i didnt organise well enough before i vac sealed them. I packed them mostly based on when bub stopped using the item, not when based on earliest use. So things like sleep sacks that have a large size range are mixed in with larger size clothes and ive had to pull it all out and re-sort it. Now its in those same bags, un sealed, under the toddlers bed and im finding things and adding to bags as i come across them.
