Put pins round seat covering tailor's frame (8)
I believe the answer is:
straddle
'put pins' is the definition.
'straddle' can be an answer for 'put' (thesaurus). I'm not sure about the 'pins' bit.
'seat covering tailor's frame' is the wordplay.
'seat' becomes 'saddle' (saddle is a kind of seat).
'covering' indicates putting letters inside.
'frame' means to remove the middle letters.
'tailor' with its middle removed is 'tr'.
'saddle' going around 'tr' is 'STRADDLE'.
'round' acts as a link.
Can you help me to learn more?
(Other definitions for straddle that I've seen before include "Go across" , "Extend over a certain area" , "Stand with legs either side of" , "Stretch legs across" , "Sit astride" .)
