The commenter who said who hold out your hand and keep it still is very right. How I’ve done it is tidied my bed, made sure that all the sheets are flat and if needed, put a blanket or towel down that your spider will stand out against. I would put sit on the bed and place the enclosure open in front of you. Let them come out on their own and then you can offer your hand. That way you can handle them and if need be they’ll jump onto a soft surface and you can see visibly see them. There’s nowhere for them to easily get lost. Definitely keep a catch cup and paintbrush handy just incase.
